About this board
The DOIT ESP-Mx DevKit (also written as ESP-Mx DevKit or Doit ESP8285 DevKit) is a low-cost Wi-Fi board built around the ESP-Mx module and Espressif's ESP8285 - an ESP8266 core with 1 MB of embedded flash. It pairs a CH340C USB-to-serial converter with a red power LED and a blue LED on GPIO16 in a breadboard-friendly layout. With flash integrated on-chip, the module stays compact, ideal for low-cost, space-constrained Wi-Fi IoT projects. In this guide, you'll find the DOIT ESP-Mx DevKit pinout, datasheet, technical specs, and setup instructions.
