DescriptionThe SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. If you open up an electronic bathroom scale， you'll find a large rat's nest of wires. The Load Sensor Combinator was created to combine the 12 wires found in a bathroom scale into the standard four-wire Wheatstone bridge configuration.This version of the SparkFun Load Sensor Combinator features a few changes that you specifically asked for! We updated the silk on the breakout to read "C/+/-" instead of "R/W/B" and moved the temperature sensor connector away from the standoff hole.You can either use four individual load sensors or simply purchase an off-the-shelf bathroom scale and hack the combinator into it rather than trying to design a base to properly mount four load sensors.This board works great with our Load Cell Amplifier breakout board； the five pins on the edge of the combinator line up directly to the five pins on the amplifier.If your amplifier and supporting electronics are more than a few inches away from the scale， an RJ45 footprint is provided. The four Wheatstone pins(E+/E-/S+/S-)as well as the shield pin are connected to twisted pairs within a standard cheap Ethernet cable. This allows the amplifier board to be placed many feet away from the scale itself.The combinator board also includes a footprint for the DS18B20 one-wire temperature sensor. This allows the user to gather the temperature of the scale in case there is a large variance between the scale and the amplifier. These three pins are accessed through the RJ45 connection as well， allowing remote temperature readings to be gathered over one twisted pair Ethernet cable.NOTE：The SparkFun Load Sensor Combinator will only work with 3 wire load sensors， it is not compatible with 4 wire load cells.

DescriptionThe SparkFun OpenScale is a simple-to-use， open source solution for measuring weight and temperature. It has the ability to read multiple types of load cells and offers a simple-to-use serial menu to configure calibration value， sample rate， time stamp and units of precision.Simply attach a four-wire or five-wire load cell of any capacity， plug the OpenScale into a USB port， open a terminal window at 9，600bps， and you'll immediately see mass readings. The SparkFun OpenScale will enable you to turn a load cell or four load sensors in a Wheatstone bridge configuration into the DIY weigh scale for your application.The OpenScale was designed for projects and applications where the load was static(like the beehive in front of SparkFun HQ)or where constant readings are needed without user intervention(for example， on a conveyor belt system). A load cell with an equipped OpenScale can remain in place for months without needing user interaction!On board the SparkFun OpenScale is the ATmega328P microcontroller， for addressing your communications needs and transferring your data to a serial terminal or to a data logger such as the OpenLog， an FT231 with mini USB， for USB to serial connection； the HX711， a 24-bit ADC for weigh scales； and the TMP102， for recording the ambient temperature of your system. The OpenScale communicates at a TTL level of 9，600bps 8-N-1 by default and possesses a baud rate configurable from 1，200bps to 1，000，000bps.Get Started with the OpenScale GuideFeaturesOperating Voltage：5VOperating Ampage：80-100mAPower Cycling above 500msSelectable 10SPS or 80SPS Output Data RateLocal External Temperature SensorsFixed Adjustable Gain

DescriptionGet with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.Note：The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 sensor consider using the Qwiic Mux Breakout.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the RV-1805 Real Time Clock Module GuideFeaturesOperating Voltage(Startup)：1.6V - 3.6VOperating Voltage(Timekeeping)：1.5V - 3.6VOperating Temperature：-40℃ - 85℃Time Accuracy：±2.0 ppmCurrent Consumption：22nA(Typ.)I2C Address：0xD2Supercapacitor for Backup Power2x Internal Oscillators2x Qwiic Connectors

DescriptionThe LIDAR-Lite v4 LED sensor is the next step in the LIDAR-Lite line. A small， lightweight， low-power optical ranging sensor. It's the first to incorporate ANT profile wireless networking technology into an optical sensor. Its built-in nRF52840 processor means that developers can create custom applications， or be operated as a stand-alone device right out of the box by using the preloaded stock application.Like the LIDAR-Lite v3 and LIDAR-Lite v3HP sensors； it can also be directly connected to an external micro-controller running a custom user application. As such， it provides a highly adaptable option for OEM and maker applications in robotics， Internet of Things， and unmanned vehicles ― or any application where an ultrasonic sensor might otherwise be used. It's perfect as the basic building block for applications where wireless capabilities， small size， light weight， low power consumption and high performance are important factors in a short-range， 10-meter， optical distance measuring sensor.The LIDAR-Lite v4 requires an external 5VDC power source and soldering is required. This Time-of-Flight ranging module uses a LED and optics for ranging. It does not use a laser； therefore， it is inherently eye-safe under normal usage.FeaturesResolution：1 cmMeasurement repeatability：As measured indoors to a 90% reflective target1 cm is equivalent to 1 standard deviationUsing "high accuracy" mode， with averaging：+/- 1 cm to 2 meters+/- 2 cm to 4 meters+/- 5 cm to 10 metersRange：5 cm to 10 meters(as measured from back of unit)Update rate：I2C = >200 Hz typicalANT(R)= up to 200 Hz to a 90% target indoors at 2m in normal operating modeInterface：I2C or ANT； user configurable for SPI using the Nordic SDKPower(operating voltage)：4.75 - 5.25 VDCCurrent consumption：2mA idle， 85mA during acquisitionOperating temperature：-20 to 60° CLED wavelength：940 nmBeam divergence：4.77°Optical aperture：14.9 mmUnit size(HxWxD)：2.1"×0.8"×0.9"(52.2×21.2×24.0 mm)Weight：14.6 g(0.5 oz)

DescriptionThink of the RedBoard Artemis as just another Arduino... That has BLE. And one megabyte of flash. And runs at less than 1mA. Oh， and it can run TensorFlow models. Ya， that too. The RedBoard Artemis takes the incredibly powerful Artemis module from SparkFun and wraps it up in an easy to use and familiar Uno footprint. We've written an Arduino core from scratch to make programming the Artemis as familiar asSerial.begin(9600). Time-to-first-blink is less than five minutes.The RedBoard Artemis has the improved power conditioning and USB to serial that we've refined over the years on our RedBoard line of products. A modern USB-C connector makes programming easy. A Qwiic connector makes I2C easy. The RedBoard Artemis is fully compatible with SparkFun's Arduino core and can be programmed easily under the Arduino IDE. We've exposed the JTAG connector for more advanced users who prefer to use the power and speed of professional tools. We've added a digital MEMS microphone for folks wanting to experiment with always-on voice commands with TensorFlow and machine learning. We've even added a convenient jumper to measure current consumption for low power testing.With 1MB flash and 384k RAM you'll have plenty of room for your sketches. The on-board Artemis module runs at 48MHz with a 96MHz turbo mode available and with Bluetooth to boot!The SparkFun RedBoard Artemis is a great platform to 'kick the tires' of this amazing module.

DescriptionNo， this isn't a tank tread， this is a 0.5m long Cable Carrier with 10x15mm bits composing its main body and two screw fasteners at each end for efficient mounting. Sometimes called a "drag chain，" each carrier can be used in projects with a large number of moving parts to protect internally installed cables， pipes， or tubes so they can be bent and moved while remaining protected. Cable carriers can most commonly been found in 3D printers and CNC machines but they can be used in any situation where you need cables or tubes to bend without risk of them being damaged or wearing out prematurely.This specific cable carrier offers inner dimensions of 10mm(height)by 15mm(wide)， an outer width of 22mm， and a bend radius of 20mm. Additionally， these carriers are thin enough to fit into an Actobotics channel， making custom slide machines or other projects even easier to manage. Much like a chain， individual links can be added or removed to make custom lengths.FeaturesInner Bit Height：10mmInner Bit Width：15mmOuter Bit Height：14Outer Bit Width：22mmMinimum Bend Radius：20mmReinforced Nylon Structure

DescriptionThe SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about 3/4 inch width or smaller(spray paint or electrical tape)on a light background. Each array features visible LEDs that point upward when the board is attached(properly)so you can see what the robot sees， brightness control right on the board， and an I2C interface for reading and power control. Here at SparkFun， the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 1/4 to 3/4 inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and is capable of showing you the strength of the IR LEDs. Illumination can be turned on and off with software to conserve power， or left on all the time for faster readings. The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled. Additionally we have added six mounting holes to the line follower with the two inner holes designed to fit our Shadow Chassis while the other four are general purpose.Note：As you know our Sun emits quite a bit of infrared light， making the SparkFun Line Follower Array much less effective in direct sunlight. Plan your projects accordingly!Features8 sensor eyes(QRE1113， like in our line sensor breakout)I2C interfaceAdjust IR brightness on the fly with a knobSwitch IR on and off with softwareSwitch visual indicators on and off with softwareInvert dark/light sight with softwareBased on the SX1509 I/O expander

DescriptionThe SparkFun Qwiic LED Stick features ten addressable APA102 LEDs， making it easy to add full color LED control using I2C. Write to individual LEDs to display a count in binary， or write to the whole strip for cool lighting effects. You can even add more LEDs to the end if you need to. We've written an Arduino library and Python package that take care of the I2C and communication to the LEDs so all you have to do is decide what color each LED should be.The LED Stick has a default I2C address of 0x23 but can be changed with a simple command， allowing you to control up to 100 LEDs(10 Qwiic LED Sticks)on a single bus! The address can also be changed to 0x22 by closing the solder jumper on the back of the board.This board is one of our many Qwiic compatible boards! Simply plug and go. No soldering， no figuring out which is SDA or SCL， and no voltage regulation or translation required!Warning：Using a lot of LEDs can draw a lot of current. Make sure to consider the power limits of your setup. If you expect your LED chain to draw more than 600mA of current， connect your external supply directly to VLED. Closing the jumper from VLED to VCC will add a 4.7uF decoupling capacitor.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionThis is SparkFun Beefy 3 FTDI Basic Breakout for the FTDI FT231X USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. Built upon the same foundation as our 3.3V SparkFun FTDI Basic Breakout， the Beefy 3 is equipped with an AP2112K voltage regulator making this FTDI basic breakout board capable of handling a current load of up to 600 mA! With the addition of a more "Beefy" voltage regulator your will now be able to power a 3.3V project directly from the FTDI. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.This board brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector. The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND， green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working， however this board now requires a Micro-B USB cable. The FTDI Cable is well protected against the elements， but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.This board was designed to decrease the cost of Arduino development and increase ease of use(the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.

DescriptionThese Clincher connectors from Amphenol FCI can be used to terminate Flat Flexible Cables(FFCs)to an easy-to-use standard header. Simply insert the end of the cable into the connector and press it closed. The teeth inside the connector will "clinch" around the conductors and break them out to three male 0.1" spaced pin headers!Though the Clincher connector can be used with FFCs， we also like to use them with our FlexiForce sensors and other flex/force sensors found in theRecommended Productssection below.Note：Please be aware that we will not be able to accept returns on this connector if it has been closed.
