We just wrapped up the NeoKey Trinkey tester, which uses a Teensy to program the SAMD21 processor and then test the USB interface. It’s a simple USB A pluggy-board with a cherry MX-compatible footprint (can use Kailh, Gateron etc!) with underlit NeoPixel and one capacitive touch pad. Simple and fun, its your new best friend! Great for adding ESC keys to old macbooks, coming soon – video.
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.
