ESP32-C3-DevKit-RUST-2

Overview

The ESP32-C3-DevKit-RUST-2 is a development board from Espressif designed specifically for embedded Rust programming education and exploration, though it is equally usable with Arduino and ESP-IDF. It is built around the ESP32-C3-MINI-1 module — a compact SIP (System-in-Package) with a RISC-V single-core processor at up to 160 MHz, 4 MB SPI flash, Wi-Fi 4 (802.11 b/g/n), and Bluetooth 5 with mesh support.

What sets this board apart from other ESP32-C3 devkits is the inclusion of two onboard sensors: the TDK InvenSense ICM-42670-P 6-DoF IMU (accelerometer + gyroscope) and the Sensirion SHTC3 digital temperature and humidity sensor. A Li-Ion battery charger is also integrated. These components make it immediately useful for environmental and motion sensing projects without any additional hardware.

The USB Type-C connector provides native USB Full Speed Serial/JTAG from the ESP32-C3 itself, eliminating the need for a separate UART bridge chip and streamlining the programming workflow. With 22 programmable GPIO pins, 2× 12-bit ADC (up to 6 channels), dual SPI, dual UART, I2C, I2S, and TWAI, the board covers all common embedded peripherals. The RUST-2 revision changed the user LED GPIO from 7 to 10.
