Hi All,
Just wanted to share a SPI/QSPI flash adapter (using one of the off-the-shelf 8-Pin SOP grippers) that I made that could be of interest to others. I am sure Saleae could make a much nicer one (and perhaps have even better noise isolation for high-speed SPI/QSPI flash debugging, possibly minimizing the need for glitch filter configs) if they wanted.
Sure, general-purpose micro/nano-grippers can do this just as well, but this option can come in handy when horizontal space is already cluttered with other probes and it is generally much quicker to connect up.
In my case I used 2x 10-pin shrouded headers, soldered a mini-bus bar across the ground pins and used silicone wiring to allow the adapter to have a good amount of play (the wires are about 4cm, could be a bit longer but I think this length worked quite well). The MSO pods are light enough that I don’t really need any supporting structure to keep it up right. If you are using just SPI, then you can just use one of the two connectors. Because of the tendency of the plastic to sometimes warp when soldering or due to just general use of connecting/disconnecting, I expect the pins to make themselves loose overtime, so I do connect/disconnect gently (using a small PCB at the connector side could have improved durability too).
- Or I could have made things a bit easier on myself by sacrificing two of Saleae’s 5-Wire harnesses.
Anyways just figured I would share in case this inspires anyone to make a better option =)
