I’m not sure the power is “dirty”, just not adequate. > Hackerboards like the Pi, Odroid, and Beaglebone are picky about > getting clean power because they're designed for lowest cost.

Under-voltage or under-wattage can cause I don’t think the issue is that the board designers cut cost - there’s power regulation on the boards. The issue is that the there are a lot of crappy power supplies that don’t come close to putting out the volts/amps/watts that they are rated for. The **Power Supplies** are made with cost cutting measures and/or false marking/advertising. Best to buy a power supply from a board reseller, that the reseller “qualifies” or recommends for the board. _______________________________________________ devel mailing list [email protected] http://lists.ntpsec.org/mailman/listinfo/devel
