Updating the test rig – Version 3

Disclaimer: I am not an expert in electronics or programming. That's the way I did it, and that's not necessarily the correct way to do it.

In the last few days I have updated my test rig once again:

  • Replaced the green “Sequin” and other LEDs with the new RGBW NeoPixel
  • Removed the bar graph LEDs and replaced them with rectangular RGB LEDs
  • Added the second MPR121 capacitive touch breakout board
  • Changed some power lines to use mainly the +5.0V from the PowerBoost module

Currently, the test rig looks like this:
