This Smart Edge Node is an industrial/home energy monitoring and switching board that bridges high-voltage AC mains power with low-voltage microcontroller logic.

The PC817X3NSZ1B is a transistor, Photovoltaic Output Optoisolator made by Sharp Microelectronics in a DIP-4 package with 4 pins.
PCBKit's library has its KiCad symbol (Isolator:PC817, from KiCad's library) and its footprint (Package_DIP:DIP-4_W7.62mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C17643522). 2 open-source boards in 1 repository on GitHub use it.
| Pin | Name | Type |
