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-H2-DevKitM-1 is an entry-level development board based on Bluetooth® Low Energy and IEEE 802.15.4 combo module ESP32-H2-MINI-1 or ESP32-H2-MINI-1U. Most of the I/O pins on the ESP32-H2-MINI-1/1U module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-H2-DevKitM-1 on a breadboard. ESP32-H2-DevKitM-1 (with ESP32-H2-MINI-1 on board) The document consists of the following major sections: Getting Started: Overview of ESP32-H2-DevKitM-1 and hardware/software setup instructions to get started. Hardware Reference: More detailed information about the ESP32-H2-DevKitM-1’s hardware. Hardware Revision Details: Revision history, known issues, and links to user guides for previous versions (if any) of ESP32-H2-DevKitM-1. Related Documents: Links to related documentation. Disclaimer and Copyright Notice: Link to the disclaimer and copyright notice. Getting Started This section provides a brief introduction of ESP32-H2-DevKitM-1, instructions on how to do the initial hardware setup and how to flash firmware onto it. Description of Components ESP32-H2-DevKitM-1 - Front The description of components starts from the ESP32-H2-MINI-1/1U module on the left side and then goes clockwise. Key Component Description ESP32-H2-MINI-1 or ESP32-H2-MINI-1U ESP32-H2-MINI-1/1U, with ESP32-H2 inside which integrates a 2.4 GHz transceiver compliant with Bluetooth ® Low Energy and IEEE 802.15.4-based technologies, supporting Bluetooth 5 (LE), Bluetooth mesh, Thread, Matter, and Zigbee. This module is specially designed for all kinds of low-power IoT applications. Pin Headers All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. For details, please see Header Block. 3.3 V Power On LED Turns on when the USB power is connected to the board. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output. USB-to-UART Bridge Single USB-UART bridge chip provides transfer rates up to 3 Mbps. ESP32-H2 USB Type-C Port The USB Type-C port on the ESP32-H2 chip compliant with USB 2.0 full speed. It is capable of up to 12 Mbps transfer speed (Note that this port does not support the faster 480 Mbps high-speed transfer mode). Boot Button Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. Reset Button Press this button to restart the system. USB Type-C to UART Port Power supply for the board as well as the communication interface between a computer and the ESP32-H2 chip via USB-to-UART bridge. RGB LED Addressable RGB LED, driven by GPIO8. This means that all color data is transmitted serially through a single data line (GPIO8) to control the color of the RGB LED. J5 Used for current measurement. See details in Section Current Measurement. 32.768 kHz Crystal [A] ESP32-H2 supports an external 32.768 kHz crystal to act as the Low-Power clock. This external Low-Power clock source enhances timing accuracy and consequently decreases average power consumption, without impacting functionality. [A] Boards with the PW number before PW-2024-02-0362 (before February 2024) does not populate a 32.768 kHz crystal by default. Start Application Development Before powering up your ESP32-H2-DevKitM-1, please make sure that it is in good condition with no obvious signs of damage. Required Hardware ESP32-H2-DevKitM-1 USB-A to USB-C (Type C) cable Computer running Windows, Linux, or macOS Note Some USB cables can only be used for charging, not data transmission and programming. Please choose accordingly. Software Setup Please proceed to Get Started, where Section Installation will quickly help you set up the development environment and then flash an application example onto your ESP32-H2-DevKitM-1.
