Description
Overview
The GP8212S-TC50-EW 4–20mA Current Generator Module is a compact, I2C-controlled analog output board designed for applications requiring a standard 4–20mA industrial current loop signal. The module operates from a 5V supply and includes an onboard MT3608 boost converter to generate the higher voltage required by the GP8212S-TC50-EW.
The PCB module can be controlled directly through an I2C interface, making it suitable for use with microcontrollers, PLCs, Arduino boards, ESP32, STM32, and other embedded systems.
