I'm looking for different ideas on making temporary connections to pads to sniff data (or even send data) to something like an eMMC (albeit perhaps at its slower 24MHz mode)
Although I'm not using a jtagulator, I Googled images of it to get an idea, and people seem to be using one of:
1: Header already on board
2: Soldering a lead
3: Both soldering a lead, and using a clip:
In my case there's no header, only ~1mm diameter pads (and in one case I'm targetting one end of a tiny SMD resistor).
I found this thing on Ali

But I can't find any reviews or YouTube vids of anyone using something like this, and thus wondering if it's a waste of money (and presumably long delivery time)?
What do folks here use?
