SparkFun Air Quality Sensor
SGP40 (Qwiic)
-
The SparkFun SGP40 Air Quality Sensor provides a measurement of the quality of the air in your room or house. The SGP40 is based on Sensirion's CMOSens® technology and uses a metal oxide (MOx) sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound (VOC) based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.

SparkFun IR Array Breakout
55 Degree FOV, MLX90640 (Qwiic)
-
It's time to say hip hip array for this IR Breakout! The MLX90640 SparkFun IR Array Breakout is equipped with a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. With this breakout you can detect surface temperatures from many feet away with an accuracy of ±1.5°C (best case). To make it even easier to get your infrared image, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

SparkFun Triple Axis Magnetometer Breakout
MLX90393 (Qwiic)
-
It's time to start utilizing the superior magnetometer, and what better way than to throw it onto an easy-to-use breakout board? The SparkFun MLX90393 Magnetometer Breakout is a triple-axis magnetic sensor board capable of sensing very small fields, while still behaving as one would expect during saturation in larger fields (like a nearby magnet). The MLX90393 breakout can be used as a compass sensor but also works well as a non-contact controller, a flow meter with a magnetic impeller, or a linear actuator position sensor. To make it even easier to to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

SparkFun Qwiic Pro Micro
USB-C (ATmega32U4)
-
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 SparkFun Qwiic Pro Micro is a revision of the original Pro Micro and is, overall, functionally the same as the previous version. The board is the same size as the original Pro Micro but we added a few additional features by shrinking down some components on the board such as a reset button, Qwiic connector, USB-C, and castellated pads (this makes it really handy for you custom keyboard creators out there)! Think the Pro Mini except with an ATmega32U4 on board and full USB functionality.

SparkFun Spectral Sensor Breakout
AS7263 NIR (Qwiic)
-
The SparkFun AS7263 Near Infrared (NIR) Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7263 Breakout is unique in its ability to communicate by both an I2C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board --- simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic shields, then stack the board on a development board. You’ll be ready to upload a sketch to start taking spectroscopy measurements in no time.

SparkFun Analog/Digital MUX Breakout
CD74HC4067
-
This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can't be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip's address select pins (S0-S3), and send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins!

SparkFun Decade Resistance Box
-
This is the SparkFun Decade Resistance Box, an involved PTH soldering kit that allows you to quickly and accurately dial in a specific resistance value between 0 and 999,990 Ω, in 10 Ω increments. The concept is simple, a decade box is a tool that contains resistors of many values that can be accessed via mechanical switches. All you need to do is just adjust the knobs to output any of the discrete resistances offered by the box. Once assembled, each kit will have controls that correspond to the digits in a decimal number - a control for the tens position, a control for the hundreds position, and so on.
