ESP32 – Different Kind Of Boards

ESP32 IC is manufactured by ESPressif, but all over the world many organization and companies are doing the development boards for different specifications. here discussed allESP32 modules.



Espressif  ESP-WROOM32 Module


ESP-WROOM-32 Front

ESP-WROOM-32 back



  • DevKitC is a development board with latest ESP32-WROM Module by ESPressif.


  • ESP32-DevKitC is a small-sized  by ESPressif and its ESP32-based development board
  • For quick and easy interface, most of i/o pins are exposed in pin headers on two side.
  • But no built in LED in board , The LED D1 is the Power Red LED for indicating power in the development board
