The ODYSSEY-STM32MP157C page lists that it wants a 12V 2A DC connector, but it doesn’t list what type of plug or polarity it requires. The schematics and PCB give a bit of an idea about the polarity, but the schematics also seem to imply the USB device port is USB 2.0 at 5V 2A while the page says 5V 3A?
HI @166291:
thank you for your feedback. the 12V 2A DC connector is 5.5x2.1mm center-positive barrel.and we will update the wiki.
