Looking for easy ways to make temporary connections to probe data from pads
marcosscriven:
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?

Hello. I'm using probes from Sensepeek.
A bit more expensive than Aliexpress, but well worth the money IMHO.
Kim Christensen:
The Aliexpress thing looks awkward and only suited for low frequency stuff. If the PCB you are probing has components on the other side, it's not going to lay flat and will "rock" when pressure is applied making the probes slip out of alignment. The Sensepeek posted above looks much better. Depends on how much you want to spend. Soldering a wire on is pretty cheap.
marcosscriven:
Ah, that looks perfect for my needs Faranight (this forum is awesome)
I think part of the issue here was not being sure what to Google. "probe" is too generic. "flying probe" seemed to be related, but more to do with industrial-level PCB testing. Sensepeek seems to call it "hands-free measurement".
