Analog to 12C Unit 4-20mA Input (STM32G030)

The Analog to 12C Unit is a single-channel 4~20mA current analogue measurement unit. It has the STM32G030F6 main control chip to communicate with the M5 host through I2C. It features switching to internally or externally powered wiring via jumper caps. There's an onboard power isolation chip and built-in op amp circuitry that accurately measures external current sensors and provides signal accuracy and system safety. It is suitable for power system equipment monitoring, motor control, energy management and automation, and industrial process control.
