This board has the same Bluetooth LE module (with ceramic antenna) that we use on Puck.js and Pixl.js, pre-programmed with Espruino. Just apply power, connect with Bluetooth LE or Serial and start writing JavaScript!

We sell pre-programmed bare modules, but this is a board with 0.1" pins, a voltage regulator, 2 LEDs and a button. It's thin, small, and very power efficient.
