The ATECC608A is a cryptographic co-processor with secure hardware-based key storage from Microchip – it can store your keys or certificates so you don’t have to worry about plaintext data or people reverse engineering your firmware. It supports SHA-256, HMAC and AES-128 algorithms which can offload computation from your main chip. This breakout will be a great addition to our Arduino and CircuitPython boards, could also be useful for SBC like Raspberry Pi if you want to keep a secret off of the SD card.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
