Olimex ESP32-C5-DevKit-Lipo Revision A Schematic
Schematic for the Olimex ESP32-C5-DevKit-Lipo development board, featuring the ESP32-C5-WROOM-1 module, LiPo battery charging, and USB-to-UART connectivity.
Overview
This schematic provides the hardware design for the Olimex ESP32-C5-DevKit-Lipo development board. The design is based on the Espressif ESP32-C5-WROOM-1-N8R4 module, which supports dual-band Wi-Fi 6 and Bluetooth 5 (LE). The board includes a TP4054-42 LiPo battery charger with an adjustable charging current of up to 800mA, a WL9005P3-33 LDO regulator for 3.3V power supply, and a CH340X USB-to-UART bridge. It features dual USB-C ports for programming and JTAG, a UEXT connector for Olimex peripheral expansion, and header pinouts compatible with the ESP32-C5-DevKitC-1 reference design. Additional components include battery and power sensing circuitry, status LEDs, and reset/boot buttons.
Use Cases
- IoT application development
- Battery-powered wireless sensor prototyping
- Wi-Fi 6 connectivity evaluation
- Embedded system hardware design reference
