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...

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off. This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even...

The Squid Button is a momentary action push switch with trailing leads that end in female header sockets that will fit over GPIO pins on a Raspberry Pi, Node MCU or Raspberry Pi Pico. To reduce the chance of accidental short-circuits when using the...
