Ah, hadn't spotted the latches. I've used something similar in the past, might still have a couple around somewhere, but my first inclination would be to convert them to standard screw types. That's assuming they would fit of course, but Anthony's photos suggest they should. Regards

Hi Licensing a legit USB ID costs money, both up front and ongoing. Writing drivers that keep up with the OS rev’s costs money. Supporting all this stuff with web sites and on the phone costs money. FTDI supports their products much better than the “other guys” you could buy from. That’s why

Hi The days of published schematics started to draw to a close 15 or 20 years ago. By the time the Z3xxx’s came out, they probably didn’t even generate a “publication ready” schematic. Troubleshooting this sort of gizmo simply does not make economic sense. Swap out the power supply, swap out
