。Description。The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell， and with some calibration you'll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale， process control or simple presence detection.。This version of the SparkFun Load Cell Amplifier features a few changes that you specifically asked for! We have separated the analog and digital supply， as well as added a 3.3uH inductor and a 0.1uF filter capacitor for digital supply. Need even more? Checkout the SparkFun Qwiic Scale. It has all the features of the HX711 but with additional library support， a true I2C interface， and no soldering required!。The HX711 uses a two-wire interface(Clock and Data)for communication. Any microcontroller's GPIO pins should work， and numerous libraries have been written， making it easy to read data from the HX711. Check the hookup guide below for more information.。Load cells use a four-wire Wheatstone bridge configuration to connect to the HX711. These are commonly colored RED， BLK， WHT， GRN and YLW. Each color corresponds to the conventional color coding of load cells：Red(Excitation+ or VCC)。Black(Excitation- or GND)。White(Amplifier-， Signal- or Output-)。Green(A+， S+ or O+)。Yellow(Shield)。The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI(electromagnetic interference). Please keep in mind that some load cells might have slight variations in color coding.。Note：Special thanks to Bodge for supplying the Library for the HX711!。Get Started with the HX711 Load Cell Amplifier Guide。Features。Operation Voltage：2.7V--5V。Operation Current：< 1.5mA。Selectable 10SPS or 80SPS output data rate。Simultaneous 50 and 60Hz supply rejection

Description。The 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.

。Description。This is the SparkFun RJ11 Breakout， two simple breakout boards for the common 6-pin RJ11 connector. These little boards can easily have one of our RJ11 6-Pin Connectors to work with common telephone cables. Each board features standard B/R/Y/G(Black/Red/Yellow/Green)labels on the top of the board to match a standard telephone wire. Additionally， each board has pin numbers on the back side that match with the pins on the connector.。Each breakout consists of two boards -- one for each end of the connections -- as well as mounting holes to help you secure your project in place.

Description。The 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!。Features。8 sensor eyes(QRE1113， like in our line sensor breakout)。I2C interface。Adjust IR brightness on the fly with a knob。Switch IR on and off with software。Switch visual indicators on and off with software。Invert dark/light sight with software。Based on the SX1509 I/O expander

Description。This tri-band GNSS antenna is ideal for GPS L1， GLONASS L1， and Beidou B2 reception. At 45x45mm it is a。large。ceramic antenna with an incredible 38dB LNA gain.。This antenna works well with the GPS-RTK providing reception of Beidou satellites where other more basic GPS antennas cannot. We've chosen to have the antenna manufactured without an enclosure to decrease the weight(45g including cable)making this antenna more ideal for rover and quad-copter applications. Additionally， the cable length has been reduced to 1m to reduce weight and to make a more clean installation.。We recommend this antenna for RTK use when combined with the ground plate. This antenna is ideal for advanced raw， RTK， and post-processed measurements of GPS， GLONASS， and Beidou constellations. If all you need is GPS and GLONASS(basic GNSS)consider our lower cost magnetic mount GNSS antenna.。Antenna is terminated with a standard SMA connector. Check out the related items below for any conversion cables you may need.。Features。Dimensions：45x45x9mm。Weight：45g including 1m cable。Frequency Range：1558 - 1615MHz。LNA Voltage：3.3 to 15VDC。Primary Antenna Gain：4dB。LNA Gain：38dB。LNA Current：<= 35mA。Termination Connector：SMA。Impedance：50Ω。Right hand polarization。Cable Length：1 meter
