M5Stack Din Meter w/ M5StampS3

The M5Stack Din Meter is a compact development board in 1/32 DIN format (45 x 22.5 mm), designed for direct installation in standard electrical cabinets or enclosures. It is powered by an M5StampS3 microcontroller (ESP32-S3) and features a 1.14-inch ST7789v2 color LCD screen.

This module includes a rotary encoder for intuitive navigation, along with a buzzer, real-time clock (RTC), and physical buttons below the screen. Power supply is flexible with a wide-range DC input (6-36 V) and a dedicated interface for a 250 mAh lithium battery with charging management. The PORTA and PORTB ports allow easy addition of I2C or GPIO peripherals via M5Stack connectors.
