The Espressif ESP32-C3-DevKit-RUST-2 Development Board is a compact development platform built around the ESP32-C3-MINI-1 module with 4MB SPI Flash, making it ideal for IoT, embedded, and wireless applications. It combines 2.4GHz Wi-Fi and Bluetooth Low Energy (BLE 5) connectivity with onboard temperature and humidity sensing, an IMU, and a Li-Ion battery charging circuit for portable designs. The board features a 32-bit RISC-V single-core processor running at 160MHz, multiple communication interfaces, and 22 GPIOs for flexible hardware expansion. A USB Type-C port, user LED, RGB LED, and accessible pin headers simplify development, debugging, and rapid prototyping. Designed for Rust and embedded development, it is suitable for smart home devices, wearable prototypes, sensor nodes, and educational projects requiring reliable wireless connectivity.
