Hi!
I got the PCB's from JLCPCB yesterday, well done. Programmed right away, tested the drivers passively, with 5V source - they work fine and drive relays much beefier, than the ones I will use in the RF deck.
Of course, as it always happens when one forgets to switch off all PCB layers and check for unconnected points, one "string" was forgotten on the PCB. I put a wire on and fixed the PCB files, the GERBER's are attached.
I ill next start working on the RF deck. Much thought has to be put in it to minimize stray anything and get the losses to minimum and I'm not sure about ETA for the new design.
All the best, guys!
