This board has the same Bluetooth LE module 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.

Features

  • Bluetooth Low Energy
  • Espruino JavaScript interpreter pre-installed
  • nRF52832 SoC - 64MHz ARM Cortex M4, 64kB RAM, 512kB Flash
  • 22 GPIO (capable of PWM, SPI, I2C, UART) on 0.1" pitch, including 7 analog inputs
  • Built in thermometer
  • NFC tag programmable from JavaScript (when antenna added)
  • 2.5v  - 16v input voltage range, drawing ~20uA while advertising.
  • Powerful (250mA, 500mA peak) MCP1703T 3.3v voltage regulator, capable of powering an ESP8266
