DinMeter v1.1 is an iterative upgrade of the DinMeter product, with the core enhancement being the main control module upgraded from Stamp-S3 to Stamp-S3A. DinMeter v1.1 adopts the 1/32 DIN standard digital meter cutout size, allowing direct installation into reserved mounting openings of mainstream equipment such as industrial control cabinets and PLC control boxes, without the need for custom brackets or panel modifications. This significantly reduces integration cost and assembly time. It supports two mounting methods窶播ouble-sided adhesive and screw hole fixation窶杯o meet installation requirements in different scenarios. The product integrates a 1.14-inch ST7789 display and a rotary encoder with button, enabling precise knob position tracking and interactive operation. An onboard RTC real-time clock, buzzer, and function buttons support scheduled reminders and wake-up functions. The power supply design is flexible, supporting a wide DC input range of 6 ~ 36V, and includes a lithium battery interface with charging circuitry to adapt to various power scenarios. In addition, the development board provides PORT.A and PORT.B expansion interfaces for easy connection of I2C and GPIO peripherals, making it suitable for various embedded instrumentation display and control input applications.
