Introduction
The ESP32-S2-DevKitM-1 is an entry-level development board featuring the ESP32-S2-MINI-1 module. This module integrates the ESP32-S2FH4 chip, which has a Xtensa® single-core 32-bit LX7 microprocessor, 128 KB ROM, and 320 KB SRAM. The board includes 4 MB of SPI flash and provides Wi-Fi (802.11 b/g/n) connectivity. All available GPIO pins are broken out to breadboard-compatible headers. It includes a USB-to-UART bridge for programming and power via a Micro-USB port. An addressable RGB LED (WS2812) is connected to GPIO18.
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.
