Description

Dial v1.1 is a high-performance, multifunctional embedded development board that has been fully upgraded from the original Dial product. 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 optimized to effectively improve wireless communication performance and user interaction experience. The product is equipped with a 1.28-inch 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. 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. This product is widely applicable in smart home control, IoT applications, smart wearables, access control systems, industrial control, and educational maker projects.

    I am using Dial to automate my sailboat

    It provides a really simple use case you just twist the dial to change the data. See my YouTube Chanel "Sailing Seahorse" for how I am using it and other M5 Stack products
