This little board will look familiar to a lot of people. It’s based on the form factor of the micro:bit that’s been popular with schools in the UK and around the world, but comes with a lot more on board.
It’s powered by an nRF52840 microcontroller which has a 64MHz ARM Cortex-M4 processor and 256kB RAM for crunching data, and Bluetooth Low Energy (BLE) for communication. On the front, the noticeable features are two buttons and a 240×240 pixel (color LCD) screen.
