ESP32-H2 DevKitM-1-N4S

The ESP32-H2 DevKitM-1-N4S is Espressif's official development board for the ESP32-H2 SoC — a purpose-built 802.15.4 + Bluetooth chip. Unlike other ESP32 variants, the H2 deliberately omits WiFi to focus on low-power mesh networking via Zigbee 3.0, Thread 1.3, BLE 5.3, and Matter 1.0.

Key Features

• BLE 5.3 — latest Bluetooth Low Energy spec with improved reliability and direction finding
• 802.15.4 dual-mode — Zigbee 3.0 and Thread 1.3 share the same radio, switchable at runtime
• Matter native — ideal end-device or coordinator in a Matter ecosystem
• No WiFi — leaner power envelope, designed to live at the edge of a mesh network
• USB-C with CH343P — reliable JTAG/serial bridge for flashing and debugging
• 96MHz RISC-V — efficient open-ISA core with hardware security features

Pinout

~24 GPIO pins broken out. GPIO0–GPIO5 are ADC-capable. All GPIO support PWM via the LEDC controller. UART is on GPIO23/GPIO24, I2C on GPIO12/GPIO22.

Use Cases

Ideal for Zigbee end-devices, Thread sleepy end nodes, Matter accessories (lights, sensors, locks), and any battery-powered smart home device that joins an existing WiFi-based border router network.
