ESP32-C3-DevKit-Lipo Revision C Schematic
Schematic for the Olimex ESP32-C3-DevKit-Lipo Rev C, featuring an ESP32-C3-MINI-1 module, integrated LiPo charger, USB-C, and UEXT connector for IoT development.
Overview
This schematic details the hardware architecture of the Olimex ESP32-C3-DevKit-Lipo Revision C development board. The design is based on the Espressif Systems ESP32-C3-MINI-1-N4 module, providing WiFi and Bluetooth connectivity via a RISC-V processor. Key power management components include the TopPower TP4054 LiPo battery charger and the Silergy SY8089AAAC synchronous step-down regulator for 3.3V power. The board includes a USB-C interface for data and power, a UEXT connector for peripheral expansion, and dedicated circuitry for battery voltage measurement and external power sensing. Peripheral features include a user button, status LEDs, and dual 9-pin extension headers for GPIO access.
Use Cases
- Battery-powered IoT sensor nodes
- Low-power WiFi and Bluetooth connectivity prototyping
- Portable electronics development
