Power through GPIO and Power Button Header

Hey guys,

my project is develloping but some questions are left...
(1)
I own a pre-production board from Kickstarter. Somewere i read, that the pre-production board should not be powered through the gpio 5V headers... is that correct and if yes: why?

(2)
There is a jumper for power (and reset). But it seems not to be a standart 2.54 mm pin header. So wich should I use?

    Hi pts,

    Please see below the reply to your enquiry

    To (1), Incorrect, the 5v should be working. You can check it out if you have Volt-meter
    How did you know that the information ? it come from?
    (2)There is a jumper for power (and reset). But it seems not to be a standart 2.54 mm pin header. So wich should I use?
    To (2), Did you mean to CN2(Power Button)/CN3(Reset), if yse, the pin header spec is 2.00mm. You can make a custom button with 2.00mm connector, or use tweezer to short two pin of the CN to activate it.

    (1) I read that here https://up-community.org/forum/public-upboardhw/302-power-connector#1611 and here https://up-community.org/wiki/Setup
    Alternative Power sources
    If your application doesn't require a lot of power, the UP board could also be powered through the 5V HAT pins
    (b](Early innovators only) pre-production revisions of the board should only be powered through the DC jack.[/b]

    (2) thx
