CN0540 PMOD CONNECTOR BLOCK P8 pinout

Hi CK3,

There is only one version of the board currently available and that is Rev B.  Any difference between the schematic and silkscreen are likely an oversight during final review.  I would trust the schematic net names over the silkscreen, because the schematic is what's used to generate the initial rats nest during the layout phase and those connects cannot be cut unless you go back and make changes to the schematic.  StuartADI  any other comments on this?

Cheers,

Brandon

OK, that makes sense. I took a look at L1_TOP: 

and L4_BOT:

in 08-059358-01-b.pdf and it does look like pin 7 is not connected, which agrees with the schematic, but not the silkscreen.

Sorry about the confusion, I'll mark this as something to fix during the next board update.

Another strange thing about the PMOD connector markings is that pins 6 and 12 are labeled 3V3, but in fact they are connected to IOREF. Furthermore, by default there is no connection between IOREF and 3V3, so, if I'm using the board with the PMOD connector and without Arduino, I need to add a jumper between P2 pins 2 and 4 in order to power the dc-to-dc stages.
