Sorry but I can't seem to find an answer to this

I'm thinking of transferring my APM2 from my quad over to one of my FPV planes and using a Minim OSD but I can't see if it's possible to hook up a battery module to give me the MAH used in the OSD ?

I see there's a module for the APM2.5, can this be used on the APM2 ?

You could use the APM 2.5 power module to sense voltage and current. The benefit being you separate the APM regulated voltage supply from your servos. And it's costs about the same as the AttoPilot sensor. Though you would need to create a breakout of the DF13 cable for the measurements. You can solder a servo cable for 5v and GND to the module as it has solder pads for this on board.

Note: if you use the DF13 cable to power the APM you will need to use the two 5v and GND wires to get 2A capacity. Each DF13 wire is rated to 1A max, use two in parallel and you get 2A :-)

Hmmm OK, thanks

Sounds like I'm better off buying a RVOSD instead

Sorry. I not sure i understand your conclusion. Both OSDs need to measure Volts and current to give you mAH used. How does RVOSD solve that?

It's because I'm not a programmer, tech head etc and get on much better with plug and play things (like the RVOSD)

 

This is what promted my aversion to using the APM2.5 sensor, I got stumped at "DF13", don't even know what that is

DF13 refers to the model of cable. It's just the 6 wire cable from the APM2.5+ Power module to the  board.

Anyway, if you want I can help you understand how to wire it to an APM2.0, but would require some basic soldering.

I hadn't heard of the RVOSD before, just looking it up on the internet now. It does seem to offer a complete plug and play solution with FPV, though for same cost you could buy a APM2.5+ with minimOSD with 915Mhz (or 433Mhz) Telemetry radios.

Bill, I Am trying to do the same thing. Do you have a diagram or schematics to help do this right?

I am using an APM2 board and powering the board with the ESC, if there is away I don't mind powering the APM2 board via this power module as well

thanks for any help you can offer
