ESP32-S2-DevKitM-1 is an entry-level development board equipped with ESP32-S2-MINI-1 module. Most of the I/O pins on the module are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount the development board on a breadboard.
ESP32-S2-MINI-1 is a generic Wi-Fi MCU module that integrates ESP32-S2FH4 chip. ESP32-S2-MINI-1 comes with a PCB antenna and features a 4 MB SPI flash.
