MiniAPM v3.1

Posted by Shane Hopcroft on May 17, 2014 at 7:29pm

Hi,

I noticed a reference to this in a blog post:

http://www.goodluckbuy.com/miniapm-v3-1-mini-ardupilot-mega-2-6-external-compass-apm-flight-controller-for-multicopter-fpv.html

It looks too-good-to-be-true to me.

I was wondering if anyone had already purchaed one of these, and if so - are they any good?

Shane.

Helyo Sergio de Faria Pereira - The XSR has a CPPM output, see the instruction manual (which comes with the product and is available on the FrSky website) for more info on that. The APM 3.1 has a CPPM input, see Andrew Gill’s comment above for a diagram.

Could someone help me connect the FrSky XSR receiver to the Mini APM 3.1?

Here's mine, just before I swapped out the APM for a naze32. Once arducopter has TPA code, it'll go back in.

    It needs TPA though. Hopefully coming in 3.3, IIRC.

Hi to all

I bought one from RTF and right now, after 2 hours of flight, every thing ok.

I use 3.2 rc 12, custom frame 440 mm, 2200 to 5000 mAh, Qbrain ESC

I dont see any difference with APM2.6. Cables are nice, for sure better not to plug and unplug 1000 times.

GPS coming with it is not so good, lot of glitch and very variable (from 5 to 12 to 5 satelites)

Last log attached.

  Hi,
  i removed my atmel32u2 from MiniAPM ... it´s fried and getting very hot.
  
  Can i use an atmega328 instead of an atmega32u2?

    No you cannot. You need to use 32u2 only. And check that you have correct model as there are few models available.

      Sorry for my ambiguous description.... the 328 cpu will not soldered on original pins.
      
      My idea is to flash a 328 with ppm from sourcecode and solder the right pins with wrap wire.
      
      (I have this 328 as spare lying around)
      
      If everything works fine, it will replaces with an 32u2-mu.

        I read i can bypass the 32u2 cpu and connect ppm sumto ch5, i have frsky ppm.
        
        Which ppsum pin goes to the APM?
