Just wondering if anyone knows if it's possible to power the board via the VIN-AM pin ? I'm working on a version of RAMPS for the Arduino Due and I'd like to power everything via one connector.
For clarification, using the VIN and GND Pins on the the Arduino headers, that will power just the Due/SAM3X8 This will not power the whole board right? for that you would want to use the DC-IN J25 JST connector or the DC-IN CN22 Barrel right?
No, the VIN and GND Pins can, theoretically, power up the whole board and not just the Arduino side (as well as the DC-IN J25 JST or the DC-IN CN22 can).
Cool, but isn't the Udoo/Pi side of the board running on 5V while I thought the Arduino Due side is all 3.3V ? That's a good point. I'm also wondering how much power can safely be passed in via that method, esp if the headers on the Udoo are connected to accessories like fans and a hard-drive.
Yes this was my concern as well.. the Due part runs at 3.3v while the i.MX6 ARM size runs at double (or more) that. Is it safe to put 7-12v in the VIN pin?
Your concerns are fair but i assure you it's absolutely possible to power up the board (of course you have to be very careful). Take a look at the schematics http://udoo.org/download/files/schematics/UDOO_REV_D_schematics.pdf
