I am one of the organizers of a tech club at our school. We are building Makerbuinos and have gotten to step 12. The kids or I have most of them working but I am at a loss with a few.
One doesn’t have power to the processor. I’ve tested it with a multimeter and no current on pins 1,7, 20 and 21 like I saw recommended to test in another topic. Any ideas? I took the screen off and made sure all the joints were good but still nothing.
The other 2 that aren’t working I can’t figure out. They have power to the chip and the screen but don’t turn on. I have a feeling they will have to be sent back but I’m open to suggestions on those as well.
