Using a power module without BEC daughterboard?

Posted by Lucas on February 13, 2014 at 2:56am

Hello guys,

I bought a Power module to have information about power consumption displayed on my OSD,

Unfortunately I bought one without the BEC daughter board so instead of supplying the 5v out for my APM it gives me the LIPO out voltage. I haven't tried to plug the VCC and the GND to the APM, I don't want to burn it.

The power port is made of 6 pins:

Inside of APM

-- GND

-- V ?

-- I ?

-- VCC

Edge of the APMboard.

I guess the V and I pins are for the "information" and the GND and VCC to power the APM board, no?

So I've tried to plug only the two middle pins I and V but it won't work, Have someone succeed to use this kind of power module, I can power the APM with a separate BEC via the power port (on VCC and GND )maybe?

        Your power port should be like that, 2 pins for the GND, the middle one are for the V and I signal and the 2 pins closest to the edge of the board is the VCC. just don't connect the VCC.
        
        I you have a 5v BEC you can connect it to the APM via this port.
        
        But be careful there are two pins for the VCC not 1, just test with a voltmeter before connecting it!
        
        I hope it would help, I didn't get your question with the lead and analogue inputs, my english is poor.

        That is also my dilemma, I don't trust the figures that are coming from the multi pin or the solder pads on the back.

    I would also like to know how people are connecting the no BEC ebay type power modules?

  Thank you!
  
  I 'm happy to know that I can use that module! I'm gonna use this BEC:
  
  Apparently it gives a clean 5V voltage...
  
  Thanks for you help I gonna try that today!
