Product Description

Description:

Beetle ESP32-C3, mainly intended for IoT applications, is a controller based on ESP32-C3 RISC-V 32bit single-core processor.

Mini Size and User-Friendly

On a coin-size board of 25*20.5 mm,The Beetle ESP32-C3 is up to 13 IO ports broken out, so you don't have to worry about running out of IO ports when making projects. Moreover, its mini size effortlessly integrates into a miniature devices and offering both powerful functions and connectivity.

More Safety

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.

Dual-Mode Communication

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, applicable to a wide range of IoT application scenarios
