Title: Has anyone mafe their own probes to test S9 Hasboards? How to test?? Post by: Dragonizer on October 08, 2019, 06:35:02 PM Hi All
I am looking to make a set of meter probes to test the resistance values on S9 board chips. I can see five test points - CLK C0 R1 B0 RST. It is impossible to get a standard set of probes in between the heatsinks onto these points without shorting tho them. Has anyone made a set, soldered a pair pf long sewing needles (don't laugh) ontp the ends of the probe ends? Also what values should i be looking for resistance wise (non powered board), what should i be testing against?? Anyone got any ideas or thoughts on this? Thanks Title: Re: Has anyone mafe their own probes to test S9 Hasboards? How to test??

There is nothing to laugh about it here , in fact the way you proposed is the only way to go about it, solder those needles there you have it ! Also what values should i be looking for resistance wise (non powered board), what should i be testing against?? there you go https://i.imgur.com/WvqmCC0.png (https://i.imgur.com/WvqmCC0.png) source and more information > https://www.youtube.com/watch?v=yAiaHwRkrC4&t=192s also if you want to test the voltage, just power the board using a normal S9 controller , someone mentioned it does pretty much what the tool in the video does, also reading the kernel log, and checking how many chips are shown,should give you a clear signal of which chip/chips to test. below is a diagram that shows signal flow between the chips https://i.imgur.com/nZnAEwl.jpg (https://i.imgur.com/nZnAEwl.jpg) Code: Green : CLK Good luck. |
