Unit Gateway H2 is an all-new form factor gateway unit built on the ESP32-H2-MINI-1-N2 chip. It features a built-in 32-bit single-core MCU based on the RISC-V architecture and integrates IEEE 802.15.4 wireless communication, supporting ZigBee, Thread, and Thread-based Matter interconnection protocols. In addition, it is equipped with a hardware encryption engine to meet the demands of high-security IoT applications. The product communicates with the M5 series host via serial (UART) through the Grove (Port C) interface to achieve data exchange. Unit Gateway H2 can flexibly serve as a gateway (such as a Thread Border Router) or a terminal device, working with the host to build cross-ecosystem interconnection, or operate independently in IoT applications. Moreover, it reserves a standard program download interface and a Type-C interface for H2 chip firmware burning and debugging. This product is suitable for smart homes, environmental monitoring, sensor networks, and low-power wireless communication nodes in various scenarios.
