I’m trying to develop some modules using an Arduino (Due), following the tutorial in grid-studies first, I’m looking for the ext5v in the store but all links seem to be down, however, quickly running one of the examples everything seems to be working just find with the power supplied by the Arduino, is the external power not needed anymore? I’m using of the early 8x8 walnut monomes if that matters.
Could someone please confirm this is still needed? (I guess it still is, just hoping its not ) and point me to an alternative to the ext5v somewhere or a schematic? Could a laptop’s usb port be used to provide the extra power during development? or could something like a 5v phone charger do?
From what I understand, it should be ok, if you power the Arduino sufficiently with an external power supply. The Arduino should deliver the standard. 500mA…
i’d generally advise making sure the grid can get ample power as when all LEDs are lit there’s a chance it’ll draw more than 500ma. best case the device will simply be disconnected. i don’t know arduino handles over-current conditions.
you could use a powered hub, or get a USB splitter cable and cut one of the data wires (as demonstrated in another thread here somewhere)
I’ll try to find the thread that explains how to us the splitter cable, if you have a link or a clue on the thread title or where to find it would be useful, I did some searching without ay luck before posting.
