DescriptionThe PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default， each channel is driven at 330mA； that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board， allowing it to be used up to the full 36V rating of the AL8805 part.Three signal inputs are provided for dimming control. You can use the PWM signal from an Arduino or your favorite microcontroller to dim each channel individually， or you can tie them all to the same PWM for simultaneous dimming. Dimming can be done by an analog voltage(20%-100% of max current by varying voltage from .5V-2.5V)or by PWM(so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V)for a full 0-100% range. A small jumper is provided for each channel to allow you to increase the drive strength from 330mA to 660mA. Two mounting holes for 4-40 or M3 screws are provided on either side of the board. They are perforated so they can be easily snapped off with a pair of pliers， if a smaller footprint is desired.Note：If you're going to use screw terminals， this board uses two different sizes. Check the related products for both sizes you'll need.Note：The PicoBuck LED Driver was made in collaboration with Ethan Zonca. A portion of each sale is given back to him.

DescriptionThe TFMini Plus is a ToF(Time of Flight)LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters(+/- 5cm up to 6m)and as far as 12 meters(+/-1% starting at 6m)! As with all LiDAR sensors， your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object， but what makes this sensor special is its size. Measuring only 35x18.5x21mm， the TFMini Plus allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.Setting itself apart from the original TFmini， the TFmini Plus has been designed with an IP65 enclosure meaning its "Dust tight water resistant"， and also passed the vibration test of drone level， which will greatly expand its application range. The TFMini Plus is easy to power at only 5V and easy to talk to using the UART communication protocol.Important：This product does not use laser light for ranging. Instead it contains an LED and optics. Many such systems are being marketed under the name "LiDAR，" although it may be more appropriate to think of this device as a "Time-of-Flight Infrared Rangefinder". It differs significantly from traditional IR rangefinders in that it uses ToF to determine range and not triangulation ― as is performed by the Sharp GP-series devices.FeaturesOperating Range - 0.1m～12m1Accuracy - ±5cm@(0.1-6m)， ±1%@(6m-12m)Distance resolution - 5mmFrame rate - 1-1000Hz(adjustable)Ambient light immunity - 70kluxOperating temperature - -20℃～60℃Enclosure rating - IP65Light source - LEDCentral wavelength - 850nmFOV - 3.6°Supply voltage - 5V±0.5VAverage current - ≦110mAPower consumption - 550mWPeak current - 500mACommunication level - LVTTL(3.3V)Material of enclosure - ABS+PCStorage temperature - -20℃～75℃Weight - 11gWire length - 30cm

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)

DescriptionKeypads are very handy input devices， but who wants to tie up seven GPIO pins， wire up handful of pull-up resistors， and write firmware that wastes valuable processing time scanning the keys for inputs? The SparkFun Qwiic Keypad comes fully assembled and makes the development process for adding 12 button keypad easy. No voltage translation or figuring out which I2C pin is SDA or SCL， just plug and go! Utilizing our handy Qwiic system， 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 breadboard.Each of the keypad's 12 buttons has been labeled 1， 2， 3， 4， 5， 6， 7， 8， 9， 0， *， and and has been formatted to into the same layout as telephone keypad with each keypress resistance ranging between 10 and 150 Ohms. The Qwiic Keypad reads and stores the last 15 button presses in First-In， First-Out(FIFO)stack， so you don't need to constantly poll the keypad from your microcontroller. This information， then， is accessible through the Qwiic interface. The SparkFun Qwiic Keypad even has software configurable I2C address so you can have multiple I2C devices on the same bus.NOTE：The I2C address of the Qwiic Keypad is 0x4B and is jumper selectable to 0x4A(software-configurable to any address). multiplexer/Mux is required to communicate to multiple Qwiic Keypad sensors on single bus. If you need to use more than one Qwiic Keypad 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 common 1mm pitch， 4-pin JST connector.

DescriptionYour 5V system can wield great power with this big， beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!The heart of the board is sealed， SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor， and an LED tells you when the relay is closed. This is kit， so it comes as through-hole parts with assembly required， which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.There are some pretty beefy traces connecting the relay to the load pins， but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load， you'll need to solder directly to the board. As always with high current and voltage， play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time， but in an enclosed area heat can build up.Note：Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity. If you're uncomfortable soldering or dealing with high voltage， please check out the IoT Power Relay.
