The SparkFun Qwiic Directional Pad adds a 5-way directional pad to your I2C bus! When connected to a microcontroller, press down on the directional pad (up, down, left, right, or center) to provide additional input for your application. The built-in RGB...

The SparkFun Soft Power Switch is a passive, hard on/off switch with software feedback and control. In other words, it's like a laptop on/off switch. A simple press will turn the system on. Another press can (with MCU intervention) turn off the system...

The 3.5mm Audio jack breakout simplifies the interfacing of audio input and output signals through the standard 3.5mm audio jack and TRRS (Tip, Ring, Ring, Sleeve) signals. It provides convenient access to the audio connections, making it easier for...

Stepper motors are used for CNC machines, 3D printers, and whenever else one needs precise, powerful motion. But to get good behavior from steppers you need a motor driver chip that can provide high bursts of current, and for smooth motion, be able to...

This version of the Ultimate GPS is even MORE Ultimate, with support for more GPS-like networks such as GLONASS, for even more coverage worldwide. It uses a slightly taller module than our classic Ultimate GPS, and uses a little more power. Otherwise its...

PIM722 -A minimal but powerful RP2350 breakout board modelled on a Pin Grid Array, with the maximum exposed pins crammed into the smallest possible space. PGA2350 is a compact RP2350 breakout designed to be embedded in projects where space is...

Detect fourteen distinct channels of light (from 380 nm to 1000 nm) with this versatile spectral sensor. The AS7343 is a 14-channel multi-purpose spectral sensor. It is optimized for reflective, transmissive and emissive measurements including color...

The USB Switch/Multiplexer allows a USB device (or multiple devices if connected via a USB hub) to be switched between two hosts, or powered off. This newer 4-pin version adds a 3.3V output which can be used to toggle the state using switches without the...

The 8086 USB-USB NULL Modem (UUNM) is a back-to-back USB to Serial converter using USB CDC Serial - meaning drivers are already built in to most modern operating systems (Linux/Windows 10/Mac OS X/Android) so you can just plug n' play! Users The...

A really sophisticated and accurate colour and luminance sensor breakout that's Raspberry Pi and Arduino-compatible. As well as detecting RGB colour and light level, it has added bells and whistles like 50/60Hz light noise rejection, a wide detection...

Breathe easy, knowing that you can track and sense the quality of the air around you with this Adafruit PMSA003I Air Quality Breakout. This sensor is great for monitoring air quality, in a compact plug-in format. Best of all, unlike almost all other...

Simple but effective - this sewable breakout board has a CR2032 coin cell battery holder soldered on and 0.1" pitch breakout pins for easy connecting. Great for powering very low-current projects, or adding a battery backup circuit to a real-time-clock...

Low cost Lithium Polymer batteries have revolutionized electronics - they're thin, they're light, they can be regulated down to 3.3V and they're easy to charge. On your phone, there's a little image of a battery cell that tells you the percentage of...

Give your plain ol' microcontroller project a lift with the Adafruit AirLift - a breakout board that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite microcontroller (like the ATmega328 or ATSAMD51), awesome...

The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low-power...

This cool mechanical encoder has five buttons (up, down, left, right and centre) and a rotary scroll wheel (with satisfying clicky detents). We've surrounded it with 24 twinkly RGB LEDs and turned it into a handy, pre-assembled I2C breakout so it's...

The SparkFun AS7262 Visible 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 AS7262 Breakout is...

This super-cute 5x5 RGB LED matrix breakout is a neat way to visualise sensor data or for simple animations or notifications, and it's Raspberry Pi and Arduino-compatible. These little matrices are ideal for visualising data from other Pimoroni...

These Simple RF receivers are the easiest way possible to add wireless control, painlessly! There's no programming, configuring or addressing - simply power the receiver with ~5 VDC and press the buttons on your RF keyfob remote. When the A button is...
