Make Your Own Qromatech

To make a simple Qromatech light strip, you will need the following items:

  • a 5V light strip
  • an ESP32 Dev board
  • a 5V power source
  • a USB cable
  • connection between ESP32 board and the light strip (see below)
    • JST connector
    • spring-loaded hook connector

Circuit diagram

Since many light strips come with connectors attached, the simplest way to hack this together is to solder a JST connector directly to the Dev board, using the Dev board for the light strip's color/timing signal and power.

If you don't have access to soldering equipment and are just wanting to test things out, you can hack something together with spring-loaded hook connectors and the JST connector.

Breadboarding, custom printed circuit boards (PCBs) are also options, but are outside the scope of getting this up and running quickly and simply.
