This is Hallowing..this is Hallowing... Hallowing! Hallowing!  Following up on 2018's most-successful-skull-shaped development board, we UPPED our -skull-shaped development board game, and re-spinned (re-spun?) the HalloWing M0 into the HalloWing M4 with MORE of everything that makes this the spoooookiest dev board. Are you the kind of person who doesn't like taking down the skeletons and spiders until after January? Well,...

Coming soon! Sign up to be notified when we have these in stock What's the size of a credit card and can run CircuitPython, MakeCode Arcade or Arduino? That's right, its the Adafruit PyBadge! We wanted to see how much we could cram into a ​3 3⁄8 × ​2 1⁄8 inch rounded rectangle, to make an all-in-one dev board with a lot of possibilities, and this is what we came up with. The PyBadge is a compact board, like we said,...

Peep dis! Have you always wanted to have another pair of eyes on the back of your head? Or outfit your costume with big beautiful orbs? The MONSTER M4SK is like the Hallowing but twice as good, with two gorgeous 240x240 pixel IPS TFT displays, driven by a 120MHZ Cortex M4 processor that can pump out those pixels super fast. You'll get the same quality display as our Raspberry Pi Eyes kit but without needing to tote around a full Linux...

Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize because of the exposed metal. Even if they're gold plated! The resistivity measurement goes up and up, so you constantly have to re-calibrate your code. Also, resistive measurements don't always work in loose soil. This design is superior with a...

This cable will let you turn a JST PH 4-pin cable port into 4 individual wires with high-quality 0.1" male header plugs on the end.

These connectors can be used with Qwiic boards and cables to easily connect sensors and drivers from one...

You've got secrets, and you want to keep them safe? Most microcontrollers are not designed to protect against snoopers, but a crypto-authentication chip can be used to lock away private keys securely. Once the private key is saved inside, it can't be read out, all you can do is send it challenge-response queries. That means that even if someone gets hold of your hardware and can read back the firmware, they wont be able to extract the...
