During the February 2018 Embedded World conference in Germany, we started toying with the idea of producing a custom Zephyr development board to highlight some of the main features of the project. We were inspired by badge boards with an electronic ink display worn on lanyards by employees of PHYTEC Messtechnik GmbH, regular contributors to the Zephyr project in areas including USB, 802.15.4, and Bluetooth.
After the show closed its doors and everyone else was busy dismantling their show booths, Zephyr team members gathered at PHYTEC’s booth. We started brainstorming details for a board that would be produced and sponsored by PHYTEC specifically for Zephyr developers. Deciding the SoC was easy enough. We picked the Nordic nRF52840 since Bluetooth and 802.15.4 support was natively available in Zephyr.
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.
