Beetle ESP32-C3, mainly intended for IoT applications, is a controller based on ESP32-C3 RISC-V 32bit single-core processor.
On a coin-size board of 25*20.5 mm, there are up to 13 IO ports broken out, so you don't have to worry about running out of IO ports when making projects. Meanwhile, li-ion battery charging management function is integrated on the board which allows to directly connect li-ion battery without extra modules, while ensuring the application size and safety.
The equipped expansion board for Beetle ESP32-C3 brings out more power sources without increasing product volume, more convenient to solder. Besides, the onboard easy-to-connect GDI saves the trouble of wiring when using a screen.
