ESP32-C3-DevKit-Lipo Development Board Schematic
Schematic for the Olimex ESP32-C3-DevKit-Lipo development board, featuring LiPo battery charging, USB-C, and the ESP32-C3-MINI-1-N4 module.
Overview
This hardware design document provides the schematic for the Olimex ESP32-C3-DevKit-Lipo development board based on the Espressif ESP32-C3-MINI-1-N4 module. The design includes a Silergy SY8089AAAC buck converter for power management, a Shanghai Belling BL4054B-42TPRN LiPo battery charger, and a USB-C interface. Key features include an ESP-PROG header for programming, battery voltage sensing circuitry, and two 9-pin extension headers for peripheral access. The board supports battery-powered operation and charging via USB-C with an integrated charger current of up to 800mA.
Use Cases
- Low-power battery-operated IoT device development
- Prototyping RISC-V based wireless applications
- Evaluation of ESP32-C3 hardware features
