M5Stack DinMeter v1.1 DIN Digital Meters
M5Stack DinMeter v1.1 DIN Digital Meters are DinMeter devices featuring an upgraded Stamp-S3A main control module. These M5Stack digital meters fit the 1/32 DIN standard digital meter cutout size, meaning the DinMeter v1.1 can be directly installed into reserved mounting openings of mainstream equipment, including industrial control cabinets and programmable logic controller (PLC) control boxes, without custom brackets or panel modifications. These digital meters support double-sided adhesive and screw hole fixation mounting methods to meet installation requirements in different scenarios.
The DinMeter integrates a 1.14" ST7789 display and a rotary encoder with button, enabling precise knob position tracking and interactive operation. An onboard real-time clock (RTC), buzzer, and function buttons support scheduled reminders and wake-up functions. The power supply supports a wide DC input range of 6V to 36V and includes a lithium battery interface with charging circuitry to adapt to various power scenarios.
