Espressif Systems ESP32-C3-MINI-1/1U

ESP32-C3-MINI-1 and ESP32-C3-MINI-1U are two general-purpose Wi-Fi and Bluetooth LE modules. The rich set of peripherals and the small size of these two modules make them an ideal choice for smart homes, industrial automation, health care, consumer electronics, etc.

At the core of both modules is ESP32-C3, a single-core Wi-Fi and Bluetooth 5 (LE) MCU, based on the open-source RISC-V architecture. It strikes the right balance of power, I/O capabilities and security, thus offering the optimal cost-effective solution for connected devices.
