Product Description

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.

Product structure

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.
J5	Used for current measurement. See details in Section Current Measurement.
32.768 kHz Crystal	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.
