What is it?

This is an ESP32-C3 board I created for building a sensor cube. To make it (more or less) energy independent a energy harvesting circuit with the BQ25504 chip is added (inspired by this project. The board can be powered with a 3.7V LiPo battery which is charged by a small solar cell.

The board has a USB-C connector for powering and programming the ESP32-C3. It has 9 GPIO Pins, UART/Tx-Rx-Pins, Ground, 3.3V & 5V Pin. On board is also a WS2812B RGB Led.

Why did you make it?

I like the ESP32-C3 and wanted to create my own PCB board. I also wanted to learn the basics of KiCAD and PCB design. I will use this board for my other project: the sensor cube.

What makes it special?

All components are placed on top of the board, so the bottom is empty/flat. As far as I have seen it's the only ESP32 board with an energy harvesting circuit on it.

It's small (25 mm x 25 mm) and square :)

Great guy, awesome product

Product was sent very fast.
Working, also came with brochure about pinout of the board, useful informations for the developer.
Great for energy harvesting use. As I have measured, module can harvest energy from like 150 mV
