ESP32 H2 Supermini Dev Board

ESP32-H2 SuperMini Development Board The ESP32-H2 SuperMini is a tiny low-power ESP32 board for Zigbee, Thread, and Bluetooth LE. It has no Wi-Fi. RISC-V core at up to 96 MHz, USB-C programming, and a stamp-size footprint for mesh endpoints, Matter nodes, and battery projects. KEY FEATURES ESP32-H2 32-bit RISC-V, up to 96 MHz IEEE 802.15.4 — Zigbee 3.0 and Thread Bluetooth 5.3 LE No Wi-Fi — use C6 if you need Wi-Fi 6 plus 802.15.4 4 MB flash, 320 KB SRAM + 4 KB low-power SRAM USB-C for power and programming (native USB Serial/JTAG) Ultra-compact SuperMini / stamp form factor BOOT and RESET buttons Works with Arduino and ESP-IDF; ESPHome support is firmware-dependent SPECIFICATIONS Category Details SoC Espressif ESP32-H2 RISC-V 32-bit single-core up to 96 MHz Memory 4 MB in-package flash 320 KB SRAM 4 KB LP SRAM 128 KB ROM Wireless IEEE 802.15.4 — Zigbee 3.0 / Thread Bluetooth 5.3 LE 2.4 GHz, 250 kbps on 802.15.4 No Wi-Fi Antenna Onboard ceramic / PCB antenna I/O Broken-out GPIO with UART, SPI, I2C, PWM, ADC 3.3 V logic Power 5 V via USB-C 3.3 V on-board regulator Buttons BOOT and RESET Size About 23 × 18 mm Home Assistant Use as a Zigbee / Thread / BLE endpoint with the matching firmware Not a Wi-Fi ESPHome node What's Included: 1 × ESP32-H2 SuperMini development board NOTES This listing is the ESP32-H2 SuperMini board only. No Wi-Fi. Pair it with a Zigbee coordinator, Thread border router, or BLE stack Logic is 3.3 V. Do not feed 5 V into GPIO First flash often needs the BOOT button held while plugging in USB-C
