M5Stack AIN4-20 Module 13.2 - for M5Core

The AIN4-20mA Module 13.2 is a module that can read sensors that provide an analog signal between 4-20mA. The analog signal is converted by the built-in microcontroller (STM32G030) to a digital value that can be read out via I2C. The module supports both sensors that already have a built-in power source (with two wires) and sensors that still require an external power source (these usually have 4 wires).
