ESP32 Drivers

Neil has developed LED Panel drivers for the ESP32 range of modules.

Example wiring and other details can be found on the LED Panel ESP32 page

Driven by Arduino

Luis says "I’ve had them working two ways one with an arduino as a basic text pattern scroller as in my first video with no dimmer control."

OEM Driver board

Luis says "Second as a single square as part of a real time video wall using original manufactures driver board and a gigabit network card."

Option 3

Luis says "But would like help on getting a third option working of modifying the existing code header file on an esp32/esp8266 which has the dimming option. That way they can be used individually as one off projects with small PSUs"
