The APM PM is compatible, except you need to modify the connecting cable. ie. you can breakout the V and I sense to servo type connectors to plug into A1 & A2 with common GND. You can solder 5V and GND wires directly to exposed solder pads on the module to a servo cable to the PWM inputs, with JP1 removed. I agree a quick tutorial on the wiki would be helpful.

I was wondering about that. I have a PM on order in the hopes I could make that mod. NIce to know it is possible.

Looking forward to your test and good luck to you getting you stuff from RC Timer.

Their logistics dept are probably run by The Three Monkeys because there have always been missing goods in my orders.

It goes like this:

1. Mispick or no pick att all (About total of USD 100 each time so their prices ends up not so good...)

2. Non relevant reply from customer service

3. Total silence

To list of sensors I could add one more: PitLab current and voltage sensor

Is even cheaper, has smaller measurement range (20, 35, 50 and 75 A) what means better resolution and more reliable, soldered signal wire connection (goldpin connector may disconnect in the flight).

Had zero issues with RCT thus far total about $1200, thinking of doing the S800 and that gimble they have one day....cant keep up with my wishlist

My wishlist is called Usain Bolt!

@scott if you look at the 'mystery port' in this post (its the power module port) http://diydrones.com/forum/topics/apm2-5-5v-vcc-schematic you just need to connect lines 3/4 to the right V/I sense on A1/A2 with a GND wire from pin 5 or 6. The sense is set to 5V range and not 3.3v as in the ATTO sensor, so not sure how to set it up in MP yet.
You could also run 5V to A1/A2 from the DF13 connector, or solder a servo lead to the pads n the PM regulator as I suggested before. If you do use power from lines 1/2 on the DF13 connector, be aware that they are 1Amp rated, so you need to connect 2wires in parallel for upto 2A max draw on them.

0 issues with RCTimer, is a good and cheap store for Latam's. I got my Quad650 from there, motors, FCs etc. The best for Argentinian is that they have International Mail Registered (HongKong Post) for $2, no taxes no Customs issues.

Any of these have higher voltage? I'm thinking about an e-bike project, but I run 10S Lipo & can't find one that can measure that high.

@Adam: it's easy to make a voltage divider to measure voltage in the range you want see http://en.wikipedia.org/wiki/Voltage_divider just make sure that you have a highe enough resistance to keep the current low
