QuinLED Dig-Octa System
Brainboard-32-8L v4
Pinout Guide
Looking for the older QuinLED Dig-Octa Brainboard-32-8L v2? Go to the v2 documentation.
The brainboard-32-8L v4 is based on the Espressif ESP32 micro-controller (see full specifications here). This makes it compatible with various software out there such as WLED or ESPixelstick or if you wish you can run your own code to run on the board.
We recommend installing firmware from https://install.quinled.info which has a lot of the below pins pre-configured for the board!
To configure it all you’ll need to know what is logically connected to the physical ports. Please see the below table for this information:
