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.

    Hmm just looked those pictures more closer.. their text says:

    Features:
    - Use APM firmware and ground station, no need to modify

    - No onboard compass, which makes this version ideal for use with multicopters and rovers

    But looking more of those pictures I can clearly see HMC5883 compass on board and no clear ways to disable it. Also it seems to have wrong memory components as all Chinese clones have. None of Chinese companies really know what are correct components for APM boards and same continues here. 

    Board seems to miss all decoupling capacitors for main CPU. I can see a lot of browning outs and weird reboots with this board. Along that it's powersystem seems to miss several protections or at least I did not see those on these pictures. 

    After some of you guys get those, please post pictures to confirm.

    Other than that, it's a neat looking small pcb :)

        Ok, why they then say that "No onboard compass" :)

        As our real APM2.6 board we really do NOT have that compass. Even cutting down traces have shown some issues on some boards. Best way to disable it 100% is by removing whole compass chip. 

        Oh well..

              Question? Do you have to do this if you have the 3DR GPS?

              Thanks in advance...

        The green Chinese characters in the first pic means:

        The solder pad pointed by the arrow here has the same functionality as the JP2 jumper on an APM. It is used for firmware upgrade.

        And white in the second pic:

        Telemetry port, pins from left to right are GND, 5V, TX, RX

        I'm surprised that there is an internal compass jumper on these boards (I hadn't noticed that before) as the spec states 'No onboard compass'. Strange.

        Out of interest, did the (external) compass work before you cut the jumper?

        Hi Dieter,

        Have you been able to test the board?

        As there is precious little independent information about these boards publicly available any review of the board would be greatly appreciated.

        Cheers,

        Shane.
