I. Product Description Details
ESP32-H2-MINI-1U-H4S is an industrial-grade model within the Espressif ESP32-H2-MINI-1U series. Developed based on the ESP32-H2 SoC, it features a compact 16.6mm × 13.2mm × 2.4mm form factor and is equipped with an external antenna connector (U-type), making it suitable for demanding industrial environments and long-range communication requirements. The ESP32-H2-MINI-1U-H4S integrates 4MB of SPI Flash (industrial high-temperature version, -40°C to +105°C), a built-in 32MHz crystal oscillator and a DC-DC converter, simplifying peripheral circuit design and reducing BOM costs.
As a BLE+IEEE 802.15.4 dual-mode module, the ESP32-H2-MINI-1U-H4S supports concurrent operation of Bluetooth 5.3 (BLE) and IEEE 802.15.4-2015 protocols, enabling simultaneous Bluetooth broadcasting/connectivity and Thread/Zigbee Mesh networking. It is fully compatible with the Matter smart home interconnectivity standard, enabling seamless cross-ecosystem coordination between multiple devices. The module utilises BLE for rapid network provisioning and Thread for stable network formation, balancing low power consumption with high reliability, making it an ideal choice for battery-powered devices.
