Hi.
I am trying to learn how to use Atmega 1280 in standalone board and this might be very noobish question but here it goes: What does schematics symbol bellow mean? Is it just open connection that you can close with wire? I could not find it using google.
Thank you very much in advance!
This is the symbol
It means a solder bridgeable link.
Normally it is open but a blob of solder closes it.
It looks like solder pads. But if you can't find it on google, it's non-standard. Can you give us a link to where you saw it. there are likely clues in the context.
whoops, that's what Mike said
It is in this schematic https://www.arduino.cc/en/uploads/Main/arduino-mega-schematic.pdf
What does it do if I solder it?
Absolutely nothing. As drawn it is just across a track.
But if you cut that track to disable the automatic reset then you can enable it again by putting a solder blob on those pads.
Lol. I did look at it again and of course it does nothing. Thank you for help. I just find schematics little overwhelming.
They should have used a solder jumper symbol with cuttable track, instead of an external track.
Leo..
