This Din Meter is a 1/32 DIN standard embedded development board featuring a 1.14" ST7789 screen and powered by an M5StampS3 as its main controller. It includes a built-in rotary encoder for precise knob position tracking, an RTC circuit, an onboard buzzer, and buttons below the screen for device interaction and alert notifications. It supports a wide voltage input range of 6-36V DC and has reserved interfaces for a lithium battery and charging circuit to accommodate a variety of projects. Additionally, the reserved PORT A and PORT B interfaces provide the expansion of I2C and GPIO devices. This product is ideal for projects involving parameter measurement and detection, smart home control, IoT projects, smart wearables, access control, and industrial control.

Note: To enter download mode, hold down the G0 button on the StampS3 before powering on, then release it after the power is on.

Power On: The device can be powered on by pressing the "WAKE" button or through an IRQ signal triggered by the RTC timer. After the wake-up signal is triggered, set the hold (G46) pin to high (1) during program initialisation to maintain power; otherwise, the device will re-enter sleep mode.

Power Off: When there is no USB external power supply, this can be achieved by pressing the RST button; or, when there is no USB external power supply, by setting HOLD (GPIO46)=0 in the program to power off the device.
