Terms of Use for Development Board The development board is intended for R&D evaluation, engineering design verification, and early-stage product development. It is provided as a convenient platform for development and testing. The development board is not intended as a mass-production component or as a finished product for end consumers; therefore, its product management approach differs from that of mass-produced chips and modules. The development board has not obtained specific national or industry certifications and is not covered under regulatory frameworks such as CE, UL, or CCC. As a result, it may not meet the requirements of such regulations. Users should ensure that their use of the development board complies with the applicable laws and regulations of the country or region in which it is used. In addition, the development board has not been designed, validated, or managed for reliability testing, production, or commercial deployment purposes. Users assume full responsibility for the correct and safe use of the product. For applications beyond the intended use of the development board, including but not limited to pre-production testing, system integration, final product delivery, or other commercial uses, the user should, before mass production and in light of its own product requirements, fully evaluate the technical suitability, reliability requirements, regulatory compliance, and system integration risks associated with such applications. The user should also complete all necessary verification, testing, and certification activities relating to system-level design, product certification, reliability validation, regulatory compliance assessment, and commercial deployment. Espressif assumes no liability arising from applications beyond the intended use of the development board. Regardless of whether the parties have entered into a supplier framework agreement, quality agreement, or any other similar agreement, the development board is not subject to any requirements or commitments therein relating to product certification, reliability management, return material analysis (RMA), product/process change notification (PCN), end-of-life (EOL) management, long-term supply commitments, or any other requirements and commitments established under a mass-production product management model.

ESP32-C3 Boards ESP32-C3-DevKitC-02 ESP32-C3-DevKitM-1 ESP32-C3-LCDkit ESP32-C3-DevKitC-RUST-2 User Guide Getting Started Description of Components Application Examples Start Application Development Contents and Packaging Hardware Reference Block Diagram Header Block Hardware Revision Details Related Documents Disclaimer and Copyright Notice Resources and Legal Notices Related Documentation and Resources Disclaimer and Copyright Notice esp-dev-kits ESP32-C3-DevKit-RUST-2 ESP32-C3-DevKit-RUST-2 Download PDF ESP32-C3-DevKit-RUST-2 [中文] This user guide is intended to help you get started with the ESP32-C3-DevKit-RUST-2 and to provide more detailed technical information for development and integration. The ESP32-C3-DevKit-RUST-2 is a development board based on the ESP32-C3-MINI-1 module, a general-purpose module featuring 4 MB of SPI flash. The board integrates full Wi-Fi and Bluetooth® Low Energy (BLE) connectivity, making it suitable for a wide range of IoT and embedded applications. In addition to the ESP32-C3, the board integrates onboard sensors and a Li-Ion battery charging circuit, enabling portable and sensor-based applications without requiring external components. Most I/O pins are routed to pin headers on both sides of the board, allowing easy access to the ESP32-C3 peripherals. Developers can connect external components using jumper wires or mount the ESP32-C3-DevKit-RUST-2 directly on a breadboard for rapid prototyping.
