Can people give tips on shops, model numbers for mosfets etc? Maybe a good addition to the AIO thread?
Yes please. And thank you!@binkinator do you want to be able to edit the OP? I already checked with @Adran_Marit
No, thank you!Yes please. And thank you!
DoneYes please. And thank you!
The mosfet attaches to the Pico by one wire and the mosfet attaches to the CPU via two wires. So you want to run 2 long wires instead of just one, eh? I personally think it’s better to keep the mosfet runs as close to the CPU as you can.Would it cause an issue if I located my mosfet directly on the pico chip itself (by hard glue or tape) and soldered wires to the capacitor on cpu? I see every image shows soldering mosfets legs directly to cpu so I'm wondering if installing longer wires to cpu will introduce timings issue or something
Even with the mosfet you are still soldering to the capacitor. I personally recommend using the hwfly flex cables if you are unsure as they line up nicelyThe thing is that I don't feel comfortable soldering legs directly to the capacitor, too much risk of removing the capacitor from cpu. But I would rather prefer to solder two very thin wires first to capacitor and then attach it to mosfet. As a matter of fact it doesn't matter to me where the mosfet will be located. I thought about putting it on pico but I can do it even next to cpu as long as I can just use some thin wires and not solder directly to capacitor. This concept scares me
Does anyone know the exact specs of the resistors? I found some 1206 and 2512 ones on aliexpress and don’t know if they’re the same. I’d like to be sure before buying it.
Also, if I use the hwfly flex cables, do I still need the resistors?
I see, thanks. So there’s no specific voltage rating for these resistors? Also, would you recommend the 1206 size?You still need resistors.
The important bit is the Ohms, you want 47 Ohm resistors.
1206 just means 12mm long by 6mm wide. If you get larger you will have to find a space to put them. 2512 is pretty darn big. You get down to 603 and they start to get more fiddly to solder.
I see, thanks. So there’s no specific voltage rating for these resistors? Also, would you recommend the 1206 size?
100% correct sir. I anguished over it for a second and thought…naw…nobody is gonna catch me. Well. Here we are.resistors has no voltage rate but power rated, i.e. 1/4W or 1/25W. dealing with signal line you could use whatever one that suit yourself best Cz only little current run through datalines
I would check aliexpress if you don't care about speed.Colleagues, does anyone have the link to purchase these SMD 47-50 ohm resistors?
