Cherry MX Switch Breakout
Cherry MX Keyswitches are top-of-the-line mechanical keyboard switches. They’re satisfyingly “clicky”, reliable up to tens-of-millions of key presses, and a standard in gaming and programming keyboards across the globe. With the SparkFun Cherry MX Switch Breakout we have made the switches more easily adaptable to breadboard or perfboard-based projects. The Cherry MX Switch Breakout is a perfect prototyping tool for projects ranging from a single-key user-input to fully-custom 101-key keyboards.

CO₂ Sensor
STC31 (Qwiic)
Do you need to be able to sense CO2 concentrations of up to 100%? If so, the STC31 is the sensor for you! The Sensirion STC31 thermal conductivity sensor has two CO2 measurement ranges: 0 to 25 vol%; and 0 to 100 vol%. The measurement repeatability is 0.2 vol%, with a stability of 0.025 vol% / °C. The measurement accuracy depends on the measurement range: 0.5 vol% + 3% measured value; 1 vol% + 3% measured value.

LilyPad Light Sensor
The LilyPad Light Sensor is a sewable breakout board with an ALS-PT19 light sensor built in and ready to use right away. Each sensor outputs voltage between 0V and 3.3V depending on the level of ambient light shining on it. As more light is applied on the sensor, more current will flow from the board through the signal tab to the microcontroller you connect the sensor to. If the sensor receives no light, no current will flow through it. In a typical indoor lighting situation, the sensor will output around 1 to 2V. Adding this board into your next e-textile or wearable project will really open up the possibilities by being able to incorporate light level sensing capabilities.

LilyPad Temperature Sensor
Detecting temperature changes has never been easier. The MCP9700 is a small thermistor type temperature sensor. This sensor will output 0.5V at 0 degrees C, 0.75V at 25 C, and 10mV per degree C. Doing an analog to digital conversion on the signal line will allow you to establish the local ambient temperature. Detect physical touch based on body heat and ambient conditions with this small sensor.

PicoBuck LED Driver
The 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 AL8860 part.

Pocket AVR Programmer
This new version uses an SMD 5x2 header. This is a simple to use USB AVR programmer. It is low cost, easy to use, works great with AVRDude, and is tested extensively on a Windows desktop. Based on Dick Streefland's USBtiny and Limor Fried's USBtinyISP. This is a low-cost programmer designed for those on a tight budget.

Pro Micro
5V/16MHz
Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface.

Qwiic Pressure/Humidity/Temp (PHT) Sensor - MS8607
The MS8607 from TE is an impressive combination pressure, humidity, temperature (PHT) sensor with accuracy of ±2mbar pressure, ±3% humidity, and ±1°C. Perfect for sensing general weather conditions the MS8607 really shines for high altitude, low pressure applications. Capable of sensing down to 10mbar, this pressure sensor separates itself from many other I2C pressure sensors like the BME280. The MS8607 is simple to use and gives the user some very powerful readings with very little power and conversion time.

Qwiic Spectral Sensor
AS7341
The AS7341 is an 11-channel spectral sensor from AMS that covers wavelengths between 350nm to 1000nm. It features eight channels that span the visible spectrum and there's a channel for Near IR, clear, and flicker detection up to 2kHz. Point a spectral sensor at an object and it measures the reflected or absorbed electromagnetic wavelengths.

SparkFun 16 Output I/O Expander Breakout
SX1509
Are you low on I/O? No problem! The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals, so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. This breakout is similar to a multiplexer or "mux," in that it allows you to get more IO from less pins. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.
