Overview
The DFRobot Beetle ESP32-C6 is one of the smallest ESP32-C6 boards available, measuring just 25×20.5mm — roughly the size of a large coin. Despite its tiny footprint, it packs the full ESP32-C6 feature set: WiFi 6, Bluetooth 5, Zigbee 3.0, Thread 1.3, and Matter support, alongside an integrated LiPo battery charger for just $4.90.
Designed explicitly for wearable applications, it is used in electronic badges, pet trackers, smart buttons, and compact IoT nodes where size and weight (17 grams) are critical. The built-in single-cell LiPo charging circuit (0.5A max) eliminates the need for an external charger module, further reducing system size and complexity.
At deep sleep current as low as 14µA, it's ideal for coin-cell or small LiPo battery-powered devices. Its 13 GPIO pins support 12-bit ADC (7 channels), 6-channel PWM, SPI, dual I2C, triple UART, I2S, and IR transceiver — covering the full range of sensor and actuator interfaces needed for compact IoT projects.
Programming via Arduino IDE or MicroPython is supported, and it integrates with DFRobot's Gravity sensor ecosystem.
