This is the Nodeconf EU 2018 Conference badge, with a few minor improvements as used in the Adobe Summit in Las Vegas. See what Adobe had to say about it here.

We only have 70 of these in stock and won't be making more unless we need to place another big order. Get yours now!

It is based on Espruino Pixl.js and runs JavaScript with the same great features, but with the Arduino headers replaced with:

  • 8 RGB LEDs in 6 zones (up, down, and 4 zone RGB LCD backlight)
  • 3 axis Accelerometer and Magnetometer
  • 4 front facing buttons
  • 2 Vibration motors (left and right)
  • On/off switch
  • LiPo Rechargeable battery
  • Battery charge from Micro USB
  • J1 and J2 connectors with 8x GPIO pins
  • J3 connector for an ESP8266 ESP01 WiFi module 

This runs the standard Pixl.js firmware, but the extra features are available via the nodeconfeu2018.js library. Full information on programming and using the badge is available at 

The badge comes with a clear perspex surround (pictured) which is up and downlit by the RGB LEDs. This can be kept as-is, laser-etched, or even just engraved by hand with a Dremel or similar as shown in the pictures.

If you'd like your surround customised, please get in touch - for an extra charge we can Laser etch the surround for you with your logo.

The design has been modified slightly since the NodeConf EU 2018 badge to fix a few issues (especially to do with WiFi module wiring) - so if there's any doubt please use the information available on  over that available on sites like

Note: The badge does not come with a lanyard.
