Steve Rodgers just completed another project using a DirtyPCB order, an isolated USB serial interface, that is available at Github:
Here is another project I just completed using a Dirty PCB order. It’s an isolated serial port using the CH340G chip and 4 Silicon Labs Si8410 digital isolators. Isolating the serial port ground from your PC can allow you to work on projects which are floating way above ground potential, or work on projects where ground loops are an issue. For more information please visit my Github site noted above.
