EC-M11-EG-C5 – USER GUIDE

Programming  #

The NORVI EC-M11-EG-C5 has a mini USB port for serial connection with the SoC for programming. Any ESP32-supported programming IDE can be used to program the controller. Follow this Guide to programming NORVI ESP32-based Based Controllers with Arduino IDE.

SoC: ESP32-WROOM32
Programming Port: USB UART
