ESP32-H2-DevKitM-1 is an entry-level development board based on Bluetooth® Low Energy and IEEE 802.15.4 combo modules ESP32-H2-MINI-1. Most of the I/O pins on the ESP32-H2-MINI-1 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 is an ultra-low-power Internet of Things (IoT) solution offering multiple protocol support on a single chip. It 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. It has: A Bluetooth LE subsystem that supports features of Bluetooth 5 and Bluetooth mesh An IEEE 802.15.4 subsystem that supports Thread and Zigbee Radio protocols coexistence in 2.4GHz band State-of-the-art power and RF performance 32-bit RISC-V single-core processor with a four-stage pipeline that operates at up to 96 MHz 320 KB of SRAM, 128 KB of ROM, 4 KB LP memory, and 4 MB SiP flash inside Reliable security ensured by: Cryptographic hardware accelerators that support AES-128/256, Hash, RSA, HMAC, ECC, digital signature, and secure boot Random number generator Permission control on accessing internal memory, external memory, and peripherals External memory encryption and decryption Rich set of peripheral interfaces and GPIOs, ideal for various scenarios and complex applications. Features: ESP32-H2-MINI-1: ESP32-H2-MINI-1, 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 Espressif's Header Block. 3.3V Power On LED: Turns on when the USB power is connected to the board. 5V to 3.3V 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 is 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.
