I have found schematics on how to drive one of these from a 5v Arduino board, but not for the ESP32 that runs at 3. Audio processing is running on one core, leaving the other for control and housekeeping stuff. Basic Library. When I found out that we stock the Wemos Lolin ESP32 OLED Display Module in the Elektor Store I couldn’t wait to get my hands on it.
