ESP32-H2 SuperMini Development Board

Program the board using the ESP-IDF framework or Arduino IDE with ESP32-H2 support. Connect via the onboard USB-C port, which provides both power and a serial COM port. Select the correct board target (e.g., 'ESP32-H2') and COM port in your IDE. Use the BOOT button to enter download mode if automatic reset fails. The board typically appears as a USB CDC device for serial communication.

The ESP32-H2 SoC supports IEEE 802.15.4 (for Zigbee and Thread), Bluetooth Low Energy 5.0, and Bluetooth Mesh. It is designed for low-power, short-range wireless IoT networks. You must flash the appropriate firmware stack (e.g., Zigbee, Thread) via ESP-IDF to utilize these protocols. The chip does not support Wi-Fi. Check Espressif's official documentation for the latest supported protocol versions and example projects.

The board is powered via the USB-C port at 5V. The operating current depends on the active wireless mode and CPU load. In active RF transmission, expect currents in the tens of milliamps. The ESP32-H2 features deep sleep modes for battery operation, where current can drop to microamp levels. For precise measurements, refer to the ESP32-H2 datasheet's electrical characteristics section and monitor the VCC line with a multimeter.

Yes, the board provides access to the ESP32-H2's ADC pins, supporting up to 5 channels. The ADC is a 12-bit SAR type, offering a resolution of 0-4095 counts. Ensure your analog sensor output matches the ADC's input voltage range (typically 0V to Vref). For accurate readings, implement noise filtering in software and consider the non-linear characteristics at the extremes of the range as noted in Espressif's technical reference manual.
