I am having an issue that is strange , the only I get the 5v power on the VDD_5V_PERIPH line is when it is connected to usb cable and pc. If I connect the power cable all the lights on the we will light up . If I power feed it by the power terminal from the 3dr quad to the servo input all lights up but there is no power on the VDD_5V_PERIPH line . The only time there is 5v on this line is when it is connected to the usb port. Look at the schematic it looks like the power path controller should handle this and I appears it is doing this on all the 3.3v lines . Any suggestions? Now don't get mad at me guys but this is an rtfhawk .
