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 many BLE boards but this one has 0.1" pins, a voltage regulator, 2 LEDs and a button. It's thin, small, and very power efficient.

  • 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
  • Dimensions: 18mm x 28mm x 4mm thick

The jury's out for me on this - follow-up

Well I'd said I'd amend my review if things changed. I eventually figured out that I was doing something silly and got this board to work with a BN019 NFC reader. This was after getting it working with an Arduino. This allowed me to compare the two, hardware and development environments. Having now done this I can up rate the Espruino; it is as good as I hoped it would be. Easy to program, nice IDE.

The jury's out for me on tihis

It seemed unusual to be able to use JavaScript but since I new and thought it would save me compiling C and uploading C I thought I would give this a go. It certainly made it quick to get started. However, I think JavaScript is too slow for my application so I'm struggling to get it to work for me. Then when I tried the online C compiler service it seems to think I have an unofficial board, which is strange. By the way, if you are not used to JavaScript you may find the language a little odd as it's all based on callbacks. If the situation improves I'll update my review.
