ISO-port Isolated USB Serial Interface
This is an isolated USB serial interface implemented with a CH340G USB to serial converter chip and 4 Silicon Labs SI8410 digital isolators.
In a standard USB serial interface, the ground coming from your PC is connected to the USB ground, and connected to the device you are communicating with. If there is a high current short to ground on the device you are connected to, a large current could flow though the USB cable which could damage your computer.
If you need to communicate with some device which is not at the ground used by the PC or could raise the ground due to large fault currents then you must use some form of isolation to prevent a large fault current from flowing.
The board has a micro usb type B connector on one end, and a 6 pin 5mm connector and 2 pin 5mm connector on the other end. The 2 pin connector can be used to feed in 3.3V or 5V to power the isolated side of the interface if there is no power coming in on the 6 pin connector. The isolated side has a red LED to indicate it is powered on. The USB side has a green LED to indicate the USB cable is plugged in, and USB power is present. There are slots the PCB underneath each Si8410 to help increase the creepage distance.
