STEMMA Friend is your I2C pal – I2C scanner demo – video. This little board is something we designed to help us with I2C device development. It’s got a SAM21 on the back, and two I2C ports (one STEMMA QT and one Grove compatible JST) We imagine it will be sort of a Swiss Army Knife of I2C hacking. First demo is a simple I2C scanner. Just tells you what addresses ACK on the I2C bus. Handy for a first check of new designs! Next up…an I2C sniffer – stay tuned!
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.
