Espressif ESP32-C3-DevKit-RUST-2 Development Board

You can program the board using Espressif's official ESP-IDF framework, the Arduino core for ESP32, or PlatformIO. Connect the USB Type-C port to your computer. The board includes a USB Serial/JTAG interface, so most modern IDEs will detect it automatically. For Rust development, you can use the esp-rs toolchain and frameworks like esp-idf-hal. Ensure you have the correct USB drivers installed if required by your operating system.

The integrated charging circuit allows you to connect a single-cell Li-Ion or Li-Polymer battery directly to the board's designated pins. It manages the charging process (typically up to 500mA), enabling the development of portable, battery-powered IoT devices without requiring an external charger IC. The battery voltage is also regulated to provide the 3.3V system power, and a status LED indicates the charging state. Always refer to the board's schematic for the correct battery connection polarity and maximum voltage specifications.

Yes, you can use these sensors with the Arduino IDE by installing the ESP32 board package and relevant sensor libraries. The sensors are connected via I2C or other digital interfaces. You will need to find and install community libraries specific to the sensor models used on the board (check the official Espressif documentation for part numbers). Initialize the sensors in your setup() function and read data in the loop(). Example code is often provided in the library repositories to help you get started quickly.

Active power consumption depends on Wi-Fi/BLE radio state, but the ESP32-C3 is designed for low-power operation. For minimal consumption, you can use the deep sleep mode, which drastically reduces current to microamps, preserving battery life. In your firmware, use the `esp_deep_sleep_start()` function (ESP-IDF) or equivalent Arduino commands. Configure a wake-up source like a timer or GPIO pin before entering sleep. Ensure all unnecessary peripherals are powered down. The onboard buck converter remains active, so measure total board current for accurate battery runtime calculations.

All 22 GPIOs are broken out to the pin headers on the board's edges. Consult the official pinout diagram to identify each pin's number and alternate functions (SPI, I2C, ADC, etc.). Note that some pins are used internally for flash memory, USB, or the onboard LEDs/buttons, restricting their use. For example, GPIOs 8-11 are often used for the embedded flash. Always check the board's schematic or pin definition header file to avoid conflicts. Most pins support digital I/O, PWM, and interrupt handling, with a subset providing analog-to-digital conversion (ADC) capability.
