RAS PI Rev 1 versus Rev 2 an issue

Post by spyker49 » Mon Jul 15, 2013 12:38 pm

Hello.



ISSUES WITH RAS PI REV 1 versus RAS PI REV 2

I just learned that the GPIO on REV1 has some pins you must not connect to: However these pins are GND pins in RAS PI REV 2



NOTE TO BOARD 3 USERS:

My board 3 MSA CB RAS PI SPI will still work with either the RAS-PI Rev 1 or Rev 2. They both have the same SPI control lines .



But for RAS PI Rev 1 the user has to cut a few ribbon wires ( open circuit - make n/c) for the RAS PI REV 1 namely pins 9, 14, 20, 25



I will issue a 26 pin GPIO ribbon cable drawing for users with RAS PI Rev 1.



FYI: The set of 20 x Boards 1-4 PCB Mk-2 panels has just arrived in Perth.



Regards

Len
