-
M5Stack Dial: Uses a conventional antenna design.
-
M5Stack Dial V1.1: The antenna design has been optimized for better signal strength and performance.
Specifications
The keys on the device are essential for user interaction and control.
-
M5Stack Dial: Features keys sized at 2.6 x 1.6 x 0.55mm.
-
M5Stack Dial V1.1: The keys have been optimized for a better tactile experience and are larger at 4.0 x 3.0 x 2.0mm.
Power Consumption
Lower power consumption is always beneficial for prolonged usage and energy efficiency.
-
M5Stack Dial: Has a conventional power consumption design.
-
M5Stack Dial V1.1: Power consumption has been optimized for lower usage.
Additional Features
Both versions come with a range of features, but the V1.1 includes several enhancements.
-
M5Stack Dial: Includes a rotary encoder, RFID detection module, RTC circuit, onboard buzzer, and under-screen buttons.
-
M5Stack Dial V1.1: In addition to the features of the original version, it also includes a 1.28-inch round TFT touchscreen, supports a wide DC input voltage range of 6~36V, and has a reserved lithium battery interface and charging circuit. It also features reserved PORT.A and PORT.B interfaces for I2C and GPIO device expansion.
Applications
Both versions are suitable for a broad application range, including smart home control, IoT applications, smart wearables, access control systems, industrial control, and educational maker projects. However, the enhanced features of the M5Stack Dial V1.1 make it more versatile and better suited for advanced applications.
