I'm not sure that I understand the difference between the Beagleboard forum and the Beaglebone forum, but thought I would try posting here as well.
I have a Beaglebone Blue connected to a GPS module via the GPS micro JST connector. I selected this one because it has +5v, which is what is needed for my GPS as opposed to 3.3v on the other UARTs. The GPS module works correctly, but my issue is I can't power it down. It's been suggested that the 5v rail can't be shut down with the battery connected, but that seems rather odd to me. The also suggested solution was to use a transistor to switch 5v power via a 3.3v GPIO pin. I suppose that's a solution but not a very elegant one if the board can be somehow configured to power off the 5v rail. It seems like this should be possible, albiet not easily accessible. There doesn't seem to be much/any documentation available about this at all. I made a Youtube video showing what's going on; https://www.youtube.com/watch?v=9xrXKRy97Yk Any suggestions appreciated, otherwise I think I'm going to have to go down the path of the transistor relay... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
