LILYGO ESP32-S2 WOOR

Overview

The ESP32-S2 WOOR is a low-cost, compact development board built around the ESPRESSIF ESP32-S2-WROOM module. The ESP32-S2 features a single-core Xtensa LX7 processor with WiFi 802.11 b/g/n connectivity but notably without Bluetooth — making it a leaner choice for WiFi-only IoT applications where reduced cost and power consumption are priorities.

The board includes 4MB of flash and 320KB of SRAM, sufficient for most IoT workloads. A 32.768KHz crystal oscillator is onboard for accurate real-time clock functionality. LiPo battery connectivity is supported via a JST connector with 500mA charging current, and BOOT, RESET, and SMD DIP switch buttons are provided.

The board operates at 2.7-3.6V working voltage and is powered from USB at 5V/1A. It is compatible with standard ESP32-S2 development tools including Arduino, ESP-IDF, MicroPython, and CircuitPython.

Firmware Compatibility

The ESP32-S2 WOOR supports Arduino IDE, ESP-IDF, MicroPython, and CircuitPython. The LilyGo-esp32s2-base GitHub repository provides sample code and pin reference documentation.
