What is The Use of M5Stack Dial?

What is M5Dial

The M5Dial is a versatile embedded development board tailored for smart home control applications. It features a 1.28inch round TFT touch screen, a rotary encoder, an RFID detection module, an RTC circuit, a buzzer and buttons located below the screen.

At the heart of the M5Dial is the M5StampS3, a micro-module based on the ESP32-S3 chip, known for its high performance and low power consumption. This device supports Wi-Fi and various peripheral interfaces, including SPI, I2C, UART and ADC.

A prominent feature of the M5Dial is its rotary encoder, which allows users to adjust settings such as volume, brightness and menu options, or control home applications such as lights and air conditioning. It also includes an RFID reader for applications such as access control and identity verification.
