I2C was never meant to go 200, 300 or 400mm but we laugh in the face of death thanks to these samples we got of some looooooooong stemma qt cables. each cable has two JST SH connectors on either end and a PVC sheathed center. we were inspired by this tweet https://twitter.com/lovyan03/status/1480867328783163396 about I2C wire interleaving with power in order to avoid cross-talk for long cables (I2C is not differential so you definitely do not want to use twisted wires!) if you look closely, the cable is flat and has the red power wire between SDA and SCL instead of having them next to each other. we’re just trying it out here with our fancy new ESP32 Feather V2 which has an onboard STEMMA QT connector – 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.
