。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

Arduino Pro Mini328-3.3V/8MHzは最小機能、小型サイズのArduinoボードで8MHzのブートローダー搭載です。マイコンの動作電圧は3.3Vで標準の5Vと異なります。レギュレーターとクロック発振子を搭載しマイコンの最小限の動作は可能ですがUno等フルスペックのArduinoが標準搭載しているUSBインターフェースは省略されFTDIのインターフェースボードを外付けする仕様となっています。オートリセットは外付けインターフェースのDTR端子が有効な場合のみサポートされます。マイコンの電源電圧は3.3Vなのでインターフェースの電圧にも制限があります。メーカーのコメントによれば入門時はUno R3でスタートし習熟したユーザーが仕様を理解した上でこのArduino Proを利用すべし、とあります。("Pro"というネーミングは"初心者お断り"の意味でしょうか…)

Description。The SparkFun Qwiic HAT for Raspberry Pi is the quickest and easiest way to enter into SparkFun's Qwiic ecosystem while still using that Raspberry Pi that you've come to know and love. The Qwiic HAT connects the I2C bus(GND， 3.3V， SDA and SCL)on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy chaining boards with different addresses， you can stack as many sensors as you'd like to create a tower of sensing power!。The Qwiic Pi HAT has four Qwiic connect ports， all on the same I2C bus. In addition， many of the useful GPIO pins on the Raspberry Pi are broken out. This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header. It has been designed to sit to the side of the Pi， allowing it to work conveniently with a Pi Tin enclosure to connect boards to the Qwiic ports.。Note：。There is a small silk error that has reversed the SDA and SCL. This is simply a cosmetic mix-up and will not impact any function with this board.。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 SparkFun Qwiic Pi HAT Guide。Features。4x Qwiic Connection Ports。Select GPIO Pins Broken Out。Pi Tin Compatibility

Description。This straight bar load cell(sometimes called a strain gauge)can translate up to 10kg of pressure(force)into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to， and proportional of， the strain(e.g. pressure or force)applied to the bar. With this gauge you will be able to tell just how heavy an object is， if an object's weight changes over time， or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.。Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 10kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows：red = E+， green = O+， black = E-， and white = O-. Additionally， these load cells offer an IP66 protection rating and feature two M4 and two M5 sized through-holes for mounting purposes.。Get Started with the Load Cell Guide。Features。80mm×12.7mm×12.7mm， 250mm Wire

Description。The SparkFun I2S Audio Breakout board uses the MAX98357A digital to analog converter(DAC)， which converts I2S(not be confused with I2C)audio to an analog signal to drive speakers. The I2S Audio Breakout converts the digital audio signals using the I2S standard to an analog signal and amplifies the signal using a class D amplifier which can deliver up to 3.2W of power into a 4Ω load. The board can be configured to output only the left channel audio， right channel， or both.。The SparkFun I2S Audio Breakout board is fairly simple， requiring only a few pin connections to get it up and working. By default the board is configured in "mono" operation， meaning the left and right signals are combined together to drive a single speaker. If you want a separate speaker for the left and right audio channels you'll need to cut the mono jumper. In addition to being able to select the audio channel output， the gain can also be configured in a few ways. The gain of the amplifier can be configured from as low as +3dB to as high as +15dB. While the channel selection can be configured on board， the gain however is controlled externally using the gain pin. By default， the board is configured for +9dB， but can be easily changed!。Get Started with the SparkFun I2S Audio Breakout Guide。Features。Supply Voltage Range：2.5V - 5.5V.。Output Power：3.2W into 4Ω at 5V.。Output Channel Selection：Left， Right， or Left/2 + Right/2(Default).。Sample Rate：8kHz - 96kHz.。Sample Resolution：16/32 bit.。Quiescent Current：2.4mA.。Filterless Class D Outputs。No MCLK Required。Click and Pop Reduction。Short-Circuit and Thermal Protection.

Description。The Raspberry Pi Zero Case has been designed to fit both the Pi Zero and the Pi Zero W. These official cases consist of several parts and protect the Raspberry Pi Zero from things like rogue wires that might short it out while still allowing full access to the board. Simply snap the RPi into the bottom half of the enclosure， then snap on a desired top. No tools required!。Each case has a standard base featuring a cut-out to allow access to the GPIO， and a choice of three lids：a standard lid， a GPIO lid(allowing access to the GPIO pins from above)and a camera lid(which， when used with the short camera cable supplied， allows the Raspberry Pi camera to be fitted neatly inside it). Additionally， each case includes a 4cm long CSI cable and four rubber feet.。Note：This case does。NOT。include a Raspberry Pi or Camera Module.
