ESP32-S2-DevKit-LiPo User Manual
User manual for the Olimex ESP32-S2-DevKit-LiPo development board, featuring Li-Po battery support, an ESP32-S2 module, and integrated charging circuitry.
Overview
This technical manual details the ESP32-S2-DevKit-LiPo development board by Olimex. It describes an open-source hardware design based on the Espressif ESP32-S2-WROOM or ESP32-S2-WROVER modules. Key features include an integrated Li-Po battery charger, a CH340 USB-to-serial converter, and a low-quiescent current MCP1700T regulator designed for battery efficiency. The document covers hardware specifications, power consumption (20uA in deep sleep), pinout descriptions, and instructions for setting up the Arduino IDE with example RGB LED code.
Use Cases
- Battery-powered WiFi IoT applications
- Handheld mobile device prototyping
- Low-power sensor monitoring
- ESP32-S2 evaluation and development
- Open-source hardware projects
