The Boardoza PC817C 2CH Isolated Level Shifter Breakout Board is a dual-channel signal level isolation and conversion module built around the Sharp PC817C optocoupler. Each channel provides complete galvanic isolation between the input and output sides, ensuring safe and reliable signal transmission between circuits operating at different voltage levels.
This board supports input and output voltages ranging from 3.3V to 12V, making it compatible with most microcontrollers, sensors, and external modules. It is an ideal choice for logic level shifting, industrial control, PLC interfacing, and noise protection in electronic systems.
