ESP32-H2-Knob

# Project Brief Introduction ESP32-H2-Knob is a multi-platform intelligent controller with a press knob in an aluminum alloy case on the front, which can read presses, rotations, and other events. The built-in magnet on the back can be firmly attached to the metal surface, making it easy to control the device. The smart knob uses ESP32-H2-MINI as the main control module and is powered by a coin cell battery. The design also has a TYPE-C interface for easy program download and debugging, as well as a two-color LED to indicate the status and a debugging interface. Supports low-power management. At present, ESP-HID, BLE-ADV, Matter Switch, and three firmware firmware are provided, and you can connect to related platforms after burning. # Firmware List: ## 1.
