M5Stack Din Meter - development module with M5Stamp S3 and 1.14" display

Description

The Din Meter is an advanced development board in the 1/32 DIN standard, equipped with a 1.14-inch ST7789 display and an M5Stamp S3 as the main control unit. Thanks to the built-in rotary encoder, the device allows for precise tracking of the knob's position. Additionally, the board features a built-in RTC chip, a buzzer, and buttons located under the screen, enabling interaction with the device and alert notifications. The device supports a wide input voltage range from 6 to 36V DC and offers dedicated connectors for connecting a lithium-ion battery and charging circuit, ensuring great flexibility in power supply. Furthermore, reserved PORTA and PORTB ports allow for expansion with I2C and GPIO devices. The Din Meter is perfect for applications in parameter measurement, smart home control, IoT projects, wearable devices, access control, industrial automation, and educational projects. The device supports multiple power modes: USB, DC, and battery-powered.
