[EOL] M5Stack Dial - ESP32-S3 Smart Rotary Knob w/ 1.28" Round Touch Screen
Description
Dial is a versatile embedded development board equipped with a 1.28-inch circular TFT touch screen, powered by the M5StampS3 as the main controller, and includes a built-in rotary encoder for precise knob position recording. Additionally, the board features an RFID detection module, RTC circuit, onboard buzzer, and a screen button for device interaction and wake-up alerts. In terms of power supply, the product supports a wide voltage input range of 6 ~ 36V DC and includes a lithium battery interface and charging circuit to meet various needs. Furthermore, the reserved PORT.A and PORT.B interfaces allow for easy expansion of I2C and GPIO devices. This product is suitable for smart home control, IoT projects, smart wearables, access control, industrial control, and educational maker projects.
