Overview
ESP32-DevKitC V4 is a small-sized ESP32-based development board produced
by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for
easy interfacing. Developers can either connect peripherals with jumper wires or mount
ESP32-DevKitC V4 on a breadboard.
To cover a wide range of user requirements, the following versions of ESP32-DevKitC
V4 are available:
• different ESP32 modules
o ESP32-WROOM-DA
o ESP32-WROOM-32E
o ESP32-WROOM-32UE
o ESP32-WROOM-32D
o ESP32-WROOM-32U
o ESP32-SOLO-1
o ESP32-WROVER-E
o ESP32-WROVER-IE
• male or female pin headers.
