DFRobot Beetle ESP32 C6 Mini low-power IoT Development Board for Wireless Smart Wearable Device Supports BLE WiFi Zigbee Thread 1.3 Battery Charging


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.

Multiple transmission protocol support to expand wireless connectivity

Boasting support for multiple communication protocols, the Beetle ESP32-C6 expands wireless connectivity options. By supporting Wi-Fi and Thread protocols, it enables the creation of Matter Wi-Fi terminal devices and Matter Thread terminal devices, facilitating seamless communication and collaboration among multiple systems and platforms in smart home setups. Additionally, the Beetle ESP32-C6 supports BLE (Bluetooth Low Energy) and Zigbee communication protocols, making it suitable for use as a Thread border router, Matter gateway, or Zigbee bridge when combined with other MCUs.

Support Wi-Fi 6 to realize ultra-low power consumption IoT devices

With Wi-Fi 6 support, the Beetle ESP32-C6 enables the realization of ultra-low-power IoT devices. As the first Espressif chip to support the Wi-Fi 6 (802.11ax) protocol, it offers improved network capacity, allowing devices to operate efficiently with low latency. Moreover, Wi-Fi 6’s Target Wake Time (TWT) technology effectively reduces device power consumption, extending battery life and ensuring long-lasting device performance.
