Beetle ESP32 - C3 (Mini RISC-V Core IoT Development Board)

The Beetle ESP32-C3 is a miniature controller based on the ESP32-C3 32-bit single-core RISC-V processor. It operates at a main frequency of 160 MHz with 400KB SRAM and 4MB Flash. The board measures 25mm x 20.5mm and supports Wi-Fi (IEEE 802.11b/g/n) and Bluetooth 5 (LE) communication. It features an onboard lithium-ion battery charging management function with a maximum charge current of 400mA. The device provides 13 digital I/O ports. An expansion board is included for easier soldering and connectivity, featuring an easy-to-connect GDI. It can be programmed via Arduino IDE, ESP-IDF, and MicroPython.

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.

For instance smart wearables, the Beetle ESP32-C3 microcontroller's mini size make it an ideal choice for intelligent wearables like smartwatches and smart glasses. It can connect with smartphones, enabling health monitoring, and delivering message notifications, it accomplishes all this without sacrificing the device's form factor or increasing its weight.
