I searched for some tutorials and online trainings and it seems like you need specific hardware usually. Getting <a href="https://docs.rust-embedded.org/book/intro/hardware.html" class="external-link" target="_blank" rel="noopener">STM32F3DISCOVERY</a> or <a href="https://embedded-trainings.ferrous-systems.com/hardware.html" class="external-link" target="_blank" rel="noopener">nRF52840 DK</a> is not practical because I will have limited use for these boards after completing training. I was almost willing to get <a href="https://docs.rust-embedded.org/discovery/microbit/02-requirements/index.html" class="external-link" target="_blank" rel="noopener">micro:bit</a> when I found out that Ferrous Systems and Espressif’s <a href="https://www.espressif.com/en/news/ESP_RUST_training" class="external-link" target="_blank" rel="noopener">announced</a> <em><strong>Rust Training on ESP32</strong></em>.</p> <h2 id="esp-rust-board"> ESP Rust Board <a class="heading-link" href="#esp-rust-board"> <i class="fa-solid fa-link" aria-hidden="true" title="Link to heading"></i> <span class="sr-only">Link to heading</span> </a> </h2> <p>It is officially called <strong>ESP32-C3-DevKit-RUST-1</strong> if you want to search for it. The board is based on successful ESP32-C3-MINI-1 module and has 6DoF IMU (ICM-42670-P), a temperature and humidity sensor (SHTC3), a Li-Ion battery charger, and a Type-C USB in familiar Adafruit Feather format. It is pretty close to <a href="https://www.adafruit.com/product/5303" class="external-link" target="_blank" rel="noopener">Adafruit ESP32-S2 Feather with BME280 Sensor</a> minus Stemma connector but with IMU sensor instead. <figure><img src="https://raw.githubusercontent.com/esp-rs/esp-rust-board/master/assets/rust_board_v1.2_diagram.png"><figcaption> <h4>ESP32-C3-DevKit-RUST-1</h4> </figcaption> </figure> </p>
