I can order one, but very much looking for a “today” thing. I need a 5v differential signal from 5v single ended, and have a bunch of the little MAX485 boards for hobbyists. Turns out they’re all counterfeit and will not run on 5VDC, probably a 3.3V silicon process? The laser ran fine for a bit then this part stopped working, and tried another and it’s heating up.
Anybody got a loose MAX485 in SOIC-8, or a 5v differential driver on a module that works? I’m hunting. Also have one ordered on Mouser for quick shipping, but there’s the “today” part. Otherwise I’ve got a workaround that’s sort of suboptimal.
Ah well. Those are what I already have- they’re not the 5v MAX485 as labeled. They look like 3.3vdd supply and 5v-tolerant inputs, that’s a common part but a different part number. 5v supply is killing them
