Description The ESP32-H2 gateway module is a stackable wireless gateway development module for M5 series hosts. Built around the ESP32-H2-MINI-1, it provides a low-power 32-bit RISC-V MCU and integrated IEEE 802.15.4 radio support for Zigbee, Thread, and Thread-based Matter interconnect applications. The ESP32-H2 gateway module helps M5 host devices build Matter over Thread end devices and multi-ecosystem IoT prototypes. It includes a hardware encryption engine for security-focused IoT designs, an 8-bit DIP switch for UART/SPI interface switching and wireless function control, and a standard program download interface for firmware burning and debugging. Because the module supports stackable M5-Bus expansion, the ESP32-H2 gateway module is suitable for smart home, industrial automation, environmental monitoring, sensor networks, and low-power wireless nodes that need Zigbee, Thread, Matter, or IEEE 802.15.4 connectivity.
