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, the li-ion battery charging management function is integrated on the board which allows for directly connecting the 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 for solder. Besides, the onboard easy-to-connect GDI saves the trouble of wiring when using a screen.
Beetle ESP32-C3 supports WiFi and Bluetooth 5 (LE) dual-mode communication that reduces the difficulty of networking, and also both Bluetooth Mesh protocol and Espressif WiFi Mesh are supported for more stable communication and a larger coverage area.
