Beetle ESP32-C6 is a mini size Arduino low-power IoT development board based on the ESP32-C6 chip, featuring a compact design with dimensions as small as a coin (25*20.5mm). The ESP32-C6 is equipped with a high-performance 160MHz RISC-V 32-bit processor, supporting communication protocols such as Wi-Fi 6, Bluetooth 5, Zigbee 3.0, and Thread 1.3. It is capable of connecting to various IoT networks using multiple communication protocols, making it ideal for use as a Matter terminal device. The development board integrates lithium battery charging management, allowing for battery charging without the need for external modules. This feature contributes to a more compact project size, making it highly suitable for wearable applications.

Highly integrated with an ultra-compact size

In a form factor no larger than a coin, the Beetle ESP32-C6 provides up to 13 IO ports, alleviating concerns about insufficient IO ports during project development. The Beetle ESP32-C6 integrates lithium battery charging management, ensuring the safe charging of lithium batteries. Moreover, this development board supports battery voltage monitoring, enabling proactive measures to be taken in case of low battery levels, guaranteeing continuous device operation.
