M5Stack NanoH2 ESP32 H2 development board with Zigbee and Thread

The M5Stack NanoH2 is an ultra-compact IoT development board based on the ESP32-H2FH4S SoC with RISC-V architecture. The 32-bit single-core processor operates at up to 96 MHz and has 320 KB of SRAM and 4 MB of Flash memory. The board supports IEEE 802.15.4 wireless protocols, providing compatibility with Zigbee, Thread, and Matter for modern smart home ecosystems. Hardware security features such as Secure Boot and Flash encryption protect the firmware. The compact design integrates an LED, an IR infrared transmitter, an RGB LED, a user button, and a USB Type-C port for power and programming. The Grove port allows flexible expansion with various M5Stack modules and sensors. The NanoH2 is suitable for smart home applications, industrial controls, consumer electronics, and low-power wireless communication nodes. Development is carried out via Arduino IDE or ESP-IDF framework.
