Power On J1 jumper missing - NanoPC T4

[chrisshelms]

Hey there,

I would like my NanoPC T4 to Autostart after power failure but I'm missing the Jumper J1 which changes the Power On Mode and sits between HDMi port and USB port http://wiki.friendlyarm.com/wiki/index. ... _Dimension

According to schematics this means I have rev 1802 and the Power On jumper was added later.

Is there any way to still change the Power On behavior to "always on" somehow?

Information is in the Wiki for the T4. Here is the direct link. It is in Chinese so use Google Translate.

You need a 300K 0402 resistor and a 1uF/16V 0603 capacitor. I hope your eyesight is good and you have a small tip soldering iron as those 0402 are small.

In that case I don't think I'll bother and just switch it back on manually after a power outage. Thanks for letting me know!
