Express post delivery (2-5 business days)

The Beetle ESP32-C3 is a coin-sized IoT development board based on the ESP32-C3 RISC-V 32-bit single-core processor. Measuring just 25 × 20.5 mm, it breaks out up to 13 GPIO pins and integrates lithium battery charging management on-board — connect a Li-ion battery directly without extra charging modules.

Supports WiFi (802.11 b/g/n) and Bluetooth 5 (LE) dual-mode communication, including Bluetooth Mesh and Espressif WiFi Mesh for extended coverage. Programmable via Arduino IDE, ESP-IDF, MicroPython, C, and Python. Comes with an expansion board that provides additional power options and a GDI connector for easy screen integration.
