  • ESP32-H2

    Espressif’s IEEE 802.15.4 + Bluetooth 5 (LE) SoC, powered by a 32-bit RISC-V core, designed for low power and secure connectivity

    ESP32-H2 combines IEEE 802.15.4 connectivity with Bluetooth 5 (LE). The SoC is powered by a single-core, 32-bit RISC-V microcontroller that can be clocked up to 96 MHz. The ESP32-H2 has been designed to ensure low power consumption and security for connected devices. ESP32-H2 has 320 KB of SRAM with 16 KB of Cache, 128 KB of ROM, 4 KB LP of memory, and a built-in 2 MB or 4 MB SiP flash. It has 19 programmable GPioses with support for ADC, SPI, UART, I2C, I2S, RMT, GDMA and LED PWM.

    Features

    Integrated IEEE 802.15.4

    Thread and Zigbee protocol supported

    ESP32-H2 combines IEEE 802.15.4 radio connectivity, which is vital to mesh architectures with low power consumption. It also makes the Thread and Zigbee protocols available, thus addressing a variety of cases in application development. ESP32-H2 has been certified as a “Zigbee-Compliant Platform” and has officially become a “Thread-Certified 1.3.0 Component”.

    Enabling Matter

    Thread end devices, Thread border router, Matter gateway

    ESP32-H2’s concurrent support for IEEE 802.15.4 and Bluetooth LE enables customers to build Matter-compliant Thread end-point devices which ensure interoperability among smart-home devices from different systems. By combining ESP32-H2 and another Espressif Wi-Fi SoC, a Thread border router or a Matter-Zigbee bridge can be built for connecting Thread or Zigbee devices onto Matter Wi-Fi networks.

    Robust Security

    Hardware security features

    ESP32-H2 can facilitate building securely connected devices through such hardware features as ECC-based secure boot, AES-128/256-XTS-based flash encryption, digital signature with ECDSA support, an HMAC peripheral for identity protection, as well as cryptographic accelerators for improved performance. With such robust security features, all connected devices can be secured at an affordable cost for users' complete peace of mind.

    Software Availability

    Supported by ESP-IDF and other Espressif SDK

    ESP32-H2 is supported through Espressif’s mature IoT Development Framework (ESP-IDF), so that our customers can benefit from their familiarity with our field-proven platform that already powers millions of connected devices. ESP32-H2 supports a production-ready ESP-Zigbee-SDK to build ready-to-use Standard Home automation devices.
