ESP32-C3 bare chip development board

Overview

The ESP32-C3 bare chip development board uses the C3FN4 chip with built-in FLASH, which is about 7.5 on Taobao. With an external ceramic antenna, the PCB reserves the corresponding Π-shaped matching circuit and the crystal oscillator 0 ohm resistor according to the official design requirements.

The measured RF performance is no different from the official module.

The BOM is for reference only, you can choose according to the value.
