Beetle ESP32 C3 (RISC-V Core Development Board) Based on ESP32-C3 RISC-V 32bit single-core processor Comes with an expansion board Onboard Lithium charging management function Support WiFi and Bluetooth 5(LE) dual-mode communication Operating Voltage: 3.3 V The Beetle ESP32 C3 (RISC-V Core Development Board) is a controller based on ESP32-C3 RISC-V 32bit single-core processor. The equipped expansion board for Beetle ESP32-C3 brings out more power sources without increasing product volume, more convenient for solder. Besides, the onboard easy-to-connect GDI saves the trouble of wiring when using a screen. Beetle ESP32-C3 supports WiFi and Bluetooth 5 (LE) dual-mode communication that reduces the difficulty of networking, and also both Bluetooth Mesh protocol and Espressif WiFi Mesh are supported for more stable communication and a larger coverage area. Beetle ESP32-C3 can be programmed by Arduino IDE, ESP-IDF, MicroPython, C, and Python are both supported.
