M5Stack Dial v1.1
The M5Stack Dial v1.1 is a high-performance, multifunctional ESP32-S3 development board that has been fully upgraded from the original Dial.
New version v1.1! The new version features the StampS3A as the main controller, further enhancing system processing power and stability. Additionally, the core module antenna and buttons have been optimised to improve wireless communication performance and user interaction experience.
The M5Dial is equipped with a 1.28" round TFT touch screen and a high-precision rotary encoder, and includes an RFID detection module, RTC circuit, onboard buzzer, and under-screen buttons to enable device interaction and wake-up alerts. It's powered and programmed via USB-C.
The power supply solution supports DC 6～36V wide voltage input and includes a lithium battery interface and charging circuit to meet diverse application needs. Furthermore, the reserved PORT.A and PORT.B interfaces facilitate the expansion of I2C and GPIO devices.
USB-C cable not included.
