powering the GTT29A - which header accepts wide voltage?

[jamesh]

I have the wide voltage (-VPT) version of the GTT29A and am successfully powering it with 5 volts on VCC at the serial header. Which header accepts the wide voltage option that the -VPT provides? The hardware manual only unambiguously mentions wide voltage at the Alternate Power Connector but that header isn't populated on mine.

Hello James,

Thank you for posting on the forum.

The VPT model may work down at 5V but it is intended to work at 9-35V.
You should be able to supply power from either of these connections (I assume that you have a -CS model):
-Extended Serial Comm/ Power Header
-I2C header

The Alternate Power Connector is only for -USB models. Sorry for the confusion.
Hope this helps.

Thank you,
Raquel

Yes, this is a -CS model and I'm happy to report that wide voltage works fine at the serial header as you suggested. Thanks!
