Here is one of my projects. Original Fluke cable is too expensive so i decided made one myself.
Circuit is basic connection of FTDI FT232RL with one LM393 at output/input powered from USB. I seen this schematic somewhere on internet but i dont have link.
PCB is little bit fancy. It has 13,7x23,20mm double sided.
The body of connector is 3D printed from PLA.
gerbers and steps are included down.
