Beetle ESP32-C3 (RISC-V chip)

Small-sized controller based on ESP32-C3, with integrated charging management, suitable for IoT projects

Beetle ESP32-C3 is a control board based on the ESP32-C3 RISC-V 32-bit single-core processor chip, designed for Internet of Things (IoT) devices.

Beetle ESP32-C3 has up to 13 IO ports in a coin-sized volume. You no longer have to worry about insufficient IO ports when making projects. At the same time, the main control board also integrates lithium battery charging management function, which can be directly connected to lithium batteries without the need for peripheral modules, while ensuring application size and safety.

The expansion board that comes with the Beetle ESP32-C3 brings out more power without increasing the size, making soldering more convenient when making projects. The onboard GDI display interface solves the wiring troubles when using the screen.

Beetle ESP32-C3 supports Wi-Fi and Bluetooth 5 (LE) dual-mode communication, which reduces the difficulty of device network configuration. It also supports Bluetooth Mesh protocol and Espressif Wi-Fi Mesh to achieve higher communication stability and larger coverage area, suitable for a wide range of IoT application scenarios.

Beetle ESP32-C3 has detailed example tutorials, through which you can easily use the wireless function of the controller to connect to IoT platforms such as Alibaba Cloud and IFTTT. At the same time, DFRobot Mall provides thousands of sensors and actuators, which also have detailed tutorials, so you can easily build your own IoT system.

Beetle ESP32-C3 can be programmed using Arduino IDE, ESP-IDF, and MicroPython. C language and python can easily manipulate the hardware.
