At SparkFun we use many Arduinos and we’re always looking for the simplest, most stable one. Each board is a bit different and no one board has everything we want, so we decided to make our own version that combines all our favorite...

The SparkFun Photon Weather Shield is an easy-to-use add-on board that grants you access to barometric pressure, relative humidity, and temperature. There are also connections on this shield to optional sensors such as wind speed,...

The CY7C65213 USB to UART serial breakout is designed to provide users with a means to access all available I/O pins on the IC, and to provide a 6-pin UART header that is compatible with other SparkFun breakout boards. This breakout has...

Are you a Java developer looking to add advanced hardware I/O capabilities to your Android or PC application? Well then the IOIO-OTG is for you! The IOIO-OTG (pronounced “yo-yo-O-T-G”) is a development board specially designed to do just...

This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).

The SparkFun Weather Shield is an easy-to-use Arduino shield that grants you access to barometric pressure, relative humidity, luminosity and temperature. There are also connections on this shield to optional sensors such as wind speed,...

The BBC micro:bit is a pocket-sized computer that lets you get creative with digital technology. Each order contains just the micro:bit board. You can code, customize and control your micro:bit from anywhere! You can use your micro:bit...

The ML8511 breakout is an easy to use ultraviolet light sensor. The MP8511 Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn...

The LilyPad ProtoSnap Plus is a sewable electronics prototyping board that you can use to explore circuits and programming, then break apart to make an interactive fabric or wearable project. Programming the ProtoSnap Plus is easy with...
