Board schematics for version 1.2.x

Post by jsgl234 » Tue Dec 18, 2018 3:44 pm

Hi everyone,

I'm currently seeing different behaviour between a version 1.0 RP and a version 1.2.14 RP when powering it using the pins (behaviour is as expected when powering using USB). There is obviously something wrong with the voltages we're providing it with but I'd like to see what the hardware differences are between the boards. Is it possible to get schematics of the newer board versions, as you could with version 1.0?

Many thanks for any help.

What kind of difference do you observe?
The only voltage needed is a +5V on expansion connector E2 pin 1 and the GND connected to pin 21/22. Works fine here without problems.
All other voltages on the expansion connectors are output voltages.
Regards
Uwe
