。Description。The SparkFun Qwiic TMP117 breakout is a high precision temperature sensor equipped with an I2C interface. It outputs temperature readings with high precision of ±0.1℃ across the temperature range of -20℃ to +50℃s with no calibration and a maximum range from -55℃ to 150℃. The SparkFun High Precision Temperature Sensor also has a very low power consumption rate which minimizes the impact of self-heating on measurement accuracy. 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 a breadboard.。The SparkFun High Precision Temperature Sensor also includes programmable temperature limits， and digital offset for system correction. While the TMP102 is capable of reading temperatures to a resolution of 0.0625℃ and is accurate up to 0.5℃， the on-board TMP117 is not only more precise but has a 16-bit resolution of 0.0078℃!。To make this breakout even easier to use， we've written an Arduino library to help you get started "Qwiic-ly." Check the Documents tab above for more information.。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.

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。Sometimes we want our projects on， but sometimes we want to turn them off for a while to save power. The SparkFun Nano Power Timer will run while only consuming minimal power(approximately 35nA)and turn your project on after a set amount of time. When you are done polling your sensors， posting data to the web， writing to your logger， or planning world domination， your microcontroller can tell the Nano Power Timer to turn off the power. No more running your microcontroller all day when you only want to read the ambient temperature once per hour.。The TPL5110 delay is configured with the use of resistors. We've added a six-way DIP switch to select one of the five preinstalled resistors. The sixth switch is attached to a pad to add your own PTH(or SMD)resistor. The delays associated with the preinstalled headers are shown on the bottom of the board for quick setup. Additionally， you can select more than one switch to combine the resistors in parallel(up to 26 options not including the custom resistor)， check out the hookup guide for a nice chart as to the total resistance and corresponding delay for each combination.。The Nano Power Timer can handle voltages between 1.8V and 5.5V as well as current up to 1.1A with times from 100ms to two hours(preconfigured settings range from 30s to 2h). You will find a button on the board which will allow you a quick override to the delay so you can turn your project on whenever you like.。Get Started with the SparkFun Nano Power Switch。Features。Supply Voltage：1.8V to 5.5V。Current consumption at 2.5V：35nA Typical(50nA Max)。Selectable Time intervals：100ms to 7200s(2 hours)。Timer Accuracy：1%

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 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.
