Dear Board Members,
my name is Wolfgang ... flying Copter in couple of years with many different bords like MultiWii, Armo-O-Kopter, Openpilot, APM, ...
This week i become a used AutoQuad board from a other pilot and himself its also by used.
Now the problem is, on the board is nothing work (no red light). First i change the recom to original 7805. When power connect (adjustable power 500ma/12v) the 7805 (near the GPS) going verry hott also the voltage regulator to 3.3v.
In addition check i came to notice the signale output pin M1 has 0,9 ohm to ground.
I think this is not normal and the reason of the problem. I search a resolution to the problem i a not able to find a connection schematic about the STM32F4 Cortex.
Can anybody check the M1 signal pin ohm to ground, ore has a connection schematic plan of the board?
Thanks verry much.
Wolfes
