Upgrade to APM 2.5 or PX4?

OK, so I've got something of a dilemma... I want to upgrade my APM board as I'm still using APM1 with the analogue sensors, but I don't know if I should go with the AMP2.5 or with the PX4?


I was going to buy a new APM2.5 but I can't seem to find any that haven't already been pre-assembled or have been pre-assembled with side-entry pins, for some reason they all seem to be top entry!!  I'd have to completely re-jig my hexa to take a top mount board and honestly don't want to do that...  

Can someone tell me if the current/voltage sensor board is actually different to the APM1?  or can I adapt the APM1 board?


the alternative for me is to go with the PX4 board, I'd prefer this one as I think that as the Arducopter code develops it will require this kind of processing power to really shine, but at the moment I don't think that the code has been made public yet?  or is functional?  although the PX4 would compliment my upcoming ground station upgrade (I've got a couple of DUE boards winging their way over from china at this very moment!)

so chime in! let me know what you think!  I'll admit I'm not adverse to doing both, but I really need side mounted pins in the APM2.5 to use it, and I'm not re-working a top entry one while there's cold beer in the fridge and nice flying day's outside...

  • Do you think ArduPilot will be upgraded to use Arduino Due?
    APM 3.0+ :-)
    I would chose APM 3.0+ with Arduino Due for now and switch to PX4 as the software gets more mature and the price drops to half.

  • so px4 will be the next arducopter board and apm 2.5 will be useless in the near futur?

  • I'm actually flying a jdrones Hexa at the moment, I've manufactured my own landing gear tho as the laser cut fiberglass was a little too fragile, so I've made some from aluminium tube & strapping with plastic screws in some critical areas to provide a suitable failure point so they're field repairable... 

    I'm hoping to get myself a laser cutter in the new year so that I can make my own frame...

    No worries. We will add that option to the site but if there's anything else we can help out with in the future don't hesitate to contact us. We can usually organise any special requests you might have even if it's not on our website. Just out of interest, which Hexa do you have? Good luck with the APM2.5, again if there's anything we can help out with we're more than happy to help.

  • Thanks for the reply David, but I've already ordered one from 3DR about 5 min after they published it!  I couldn't see a way to order just the board from your site however, it seems to be bundled with a GPS...

    Hi Jesse,

    We are an Australian Distributor for APM and would be more than happy to help. We have APM's in stock (unsoldered, side pins and top entry) as well as PX4's. If you have any other questions or would like help in any way please let us know. You can see our online store at www.baskindustries.com/aerospace



  • I might have a look at the PX4 in another month or so when my bank account recovers from my Christmas spending spree!  is the developer release a testing version of the Arducopter code?  

  • Thanks Chris!  I was quietly hoping that you might chime in with something like that :-D  I'll order one very shortly!

    The side entry version is now available:

    Jess, we'll be releasing a side-entry version of APM 2.5+ in an hour or two. 

    PX4 is in developer release now. Full easy-to-use UAV software (ArduCopter) will not be released to the public until mid-year (we're targeting June)
