I cannot count how many PCBs I did with various quick connect ideas to have a fast way to debug..
- Chop a PCI connector and have edge fingers on the PCB
- Skedd connectors
- Micro usb with a toggle switch or solder blob to switch between SWD/UART or USB
- Low profile usb-c and have D+/- as normal, and RX/TX over the accessory pins (like audio)
- Pogo pin clips
- GH1.25 connectors
- Tag-connect meh
- If thickness of pcb allows, your PCB can plug directly into a USB-A port (Thicc pcb) or if its too thin, it can plug into a male usb-c connector from a charger cable(might bend some pins though)
etc. etc.
So just like the author, anything but Dupont connectors ;)
