A tiny, RGBW-illuminated, clickable Trackball Breakout that's perfect for adding navigation or control to your Raspberry Pi or Arduino projects. We've taken a trackball module from everyone's favourite fruit-flavoured phone and added a bunch of clever...

A sophisticated, hackable, 32x24 pixel thermal camera breakout! Use it to monitor the temperature of your CPU or coffee pot, or to build your own heat-seeking night vision camera. Works with Raspberry Pi or Arduino. It's perfect for building into...

This light and proximity sensor detects light over a wide dynamic range (0.01 lux to 64,000 lux) and proximity within a short range of ~5cm. The LTR-559 is the same sort of sensor that you'd find next to the camera in your phone to detect when it's next...

An all-singing, all-dancing time of flight distance sensor that uses PEW PEW LASERS (low-powered ones), our VL53L1X breakout is easy to use with Raspberry Pi or Arduino alike! These low-power-laser-based time of flight sensors have great accuracy and...

Measure changes in the concentration of gases including carbon monoxide (CO), nitrogen dioxide (NO2), and ammonia (NH3) with this Breakout Garden compatible I2C breakout. The MICS6814 sensor comprises three semiconductor gas sensors in a single package,...

Crisp, high-res, with great viewing angles (IPS), this 1.3" square, 240x240 pixel, colour LCD will add some pizzazz to your Raspberry Pi or Arduino projects. The square form-factor of this display makes it great for cramming lots of information...

A fast and precise environmental sensor that can measure temperature, pressure, and altitude. Our BMP280 breakout is Raspberry-Pi and Arduino-compatible. If you're looking for a simple temperature and pressure sensor, then this is the one to pick. It's...

A minimal RP2040 breakout board wrangled into a Pin Grid Array, with 8MB flash and a maximal dash of retraux style. PGA2040 is a compact RP2040 breakout intended for the most svelte and embeddable of projects. It contains only the components necessary to...

Measure indoor air quality—total volatile organic compounds (TVOC) and equivalent CO2 (eCO2)—with this digital sensor for Raspberry Pi and Arduino. The SGP30 sensor measures two different types of gases: volatile organic compounds (like...

With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when it's time to turn around and make that project of yours run on a battery or solar? Sure you could...

Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer?  Sure you can program an Arduino or Trinket to talk to these devices and your...

It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 42% when it feels more like 77%. Enter...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the...

Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be...

"You see, wire telegraph is a kind of a very, very long cat.  You pull his tail in New York and his head is meowing in Los Angeles.  Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there...

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is...

The IS31FL3731 will let you get back to that classic LED matrix look, with a nice upgrade! This I2C LED driver chip has the ability to PWM each individual LED in a 16x9 grid so you can have beautiful LED lighting effects, without a lot of pin...

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The...

Make your own custom HDMI cable or HDMI interface with ease, using this HDMI Plug to Breakout. You get a nice solid PCB with an HDMI plug and through hole pads that you can solder to assemble your own wiring jigs. You can add in some terminal blocks to...
