ESP32-DevKit-LiPo User's Manual
User manual for the Olimex ESP32-DevKit-LiPo development board, featuring Li-Po battery support, ESP32 modules, and low-power operation for IoT applications.
Overview
This document is the user manual for the ESP32-DevKit-LiPo, an open-source development board from Olimex based on Espressif Systems' ESP32 modules. The board features a built-in Li-Po battery charger and connector, designed for high reliability and handheld applications. It supports deep sleep modes down to 10uA and includes battery measurement and external power sense circuits. Available variants include the ESP32-WROOM-32E, the ESP32-WROOM-32UE with external U.FL antenna, and the ESP32-WROVER-E with 8MB PSRAM. The manual provides technical specifications, pinout descriptions, power consumption data, and setup instructions for the Arduino IDE and ESP-IDF.
Use Cases
- Battery-powered WiFi and Bluetooth devices
- Handheld IoT applications
- Remote sensor nodes with deep sleep requirements
- Prototyping with ESP32-WROOM and WROVER modules
- Portable electronics requiring integrated battery management
