The LTR390 is one of the few low-cost UV sensors available, and it's a pretty nice one! With both ambient light and UVA sensing with a peak spectral response between 300 and 350nm. You can use it for measuring how much sun you can get...

This is the FeatherWing Doubler - a prototyping add-on and more for all Feather boards. This is similar to our FeatherWing Proto except there are two! The magic of the Doubler comes when stacking a Feather and another board on top of the...

Little clicky switches are standard input "buttons" on electronic projects. These are just like our Colorful Round Tactile Button Switch Assortment, but already assembled onto a PCB - they even have a pull-up resistor installed! The pins...

This is the FeatherWing Tripler - a prototyping add-on and more for all Feather boards. This is similar to our FeatherWing Proto except there are three! The magic of the Tripler comes when you want to connect your Feather to two other...

Store your project safe and sound in this nice weatherproof box with a clear top. We picked up this box because we like the machinable ABS plastic body and tough clear polycarbonate cover, the built in weatherproof gasket seal, and the...

If you're unfamiliar with mecanum wheels, this Matching Left & Right pack of 48mm Diameter Mecanum Wheels may resemble everyday chunky wheels Frankenstein'd out of mini hair curler rollers. In reality, they are very cool, omnidirectional...

Description Give your Arduino project a lift with the Adafruit AirLift Shield - a shield that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite Arduino-compatible ( like the Metro M4 or the classic...

For precise motion control, GT2 belts and pulleys offer excellent precision at a great price. This pulley is meant for use with GT2 6mm wide belts only - MXL belts will slip due to the different tooth profile. This pulley has 20 teeth,...

The Adafruit Feather nRF52 Bluefruit is another easy-to-use all-in-one Bluetooth Low Energy board, with a native-Bluetooth chip, the nRF52832! It's our take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB...

What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy nRF52840 Express featuring the Nordic nRF52840 Bluetooth LE processor! Teensy & powerful, with an fast nRF52840 Cortex M4 processor running at 64 MHz and...

This I2C digital temperature sensor is one of the more accurate/precise we've ever seen, with a typical accuracy of ±0.25°C over the sensor's -40°C to +125°C range and precision of +0.0625°C. They work great with any microcontroller...

This cable will let you turn a JST PH 4-pin cable port into 4 individual wires with high-quality 0.1" female sockets on the end. We're carrying these to match up with any of our boards with 'STEMMA' connectors on them such as the...
