Dial v1.1

SKU:K130-V11

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.

Power On/Off

Power On/Off
Power On: When there is no external USB power supply (battery only), the device can be woken up by pressing the "WAKE" button or by an IRQ signal triggered by the RTC timer. After waking up, the HOLD (GPIO46) pin must be set to high (1) during program initialization to maintain power, otherwise the device will re-enter sleep mode.
Power Off: Similarly, when there is no external USB power supply (battery only), the device can be turned off by pressing the RST button or by setting the HOLD (GPIO46) pin to low (0) in the program.
