Dial v1.1 is a high-performance, multifunctional embedded development board that represents a comprehensive upgrade of the original Dial product. The new version adopts the all-new StampS3A main controller, further enhancing system processing power and stability; at the same time, the core module’s antenna and keys have been optimized, effectively improving wireless communication performance and user experience. The product features a 1.28-inch round TFT touchscreen and a high-precision rotary encoder, and it comes with a built-in RFID detection module, RTC circuit, onboard buzzer, and under-screen buttons, enabling device interaction and alert wake-up functions. Its power supply supports a wide DC input voltage of DC 6~36V and includes a reserved lithium battery interface and charging circuit to meet diverse application requirements. Additionally, 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.
