4-Channel Analog to 12C 13.2 Module 4-20mA Input (ST32G030)The 4 Channel Analog to 12C 13. 2 Module is a quad channel 4~20mA current analogue acquisition module. It has the STM32G030F6 main control chip and a dedicated acquisition chip with isolation to communicate with the M5 host for I2C communication. It supports 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
