About this board
Section titled “About this board”The reference ESP32-C3 devkit — single-core RISC-V with WiFi and BLE, Espressif’s small and cheap tier. The instruction set is the only real difference from a sketch’s point of view: the Arduino API, the peripherals and the language trio are the same as on the classic ESP32.
