Hi,
I noticed a reference to this in a blog post:
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?

Works, connect frsky ppm to pin36 with 1k resistor
Anyone who use this miniapm in a 250 copter?
I have strange problems regarding baro, motor pulses fast up/down. Reducing alt P rate to half didn´t resolve the problem.
With 2S lipo the baro seems better, but 3s is preferred. I didn´t start autotune before, can autotune help to improve the baro stanility?

Yes, my baro is covered with foam and a top/bottom case.
Logs see here and thread.. it makes me crazy.

It seems my baro has some problems ..see here:
It´s only a short notice and then it´s gone .. strange
Hi All, I have bought a few as I wanted to try it out on my Mini250mm as well. I have powered them on and all is good.. tested them with APM Planner Tests and all was okay there as well.
I will start to build out an new mini for testing in the next few weeks... but i have some photos to share on Pin-Outs if it helps.

I have seen some clever ways of hooking up the GPS and Compass, but no-one has shown how they have hooked up their inputs (Rx) or outputs (motors/servos).
If anyone has worked out an elegant way of doing this could they please post pictures.
I like the way you have hooked up the GPS/compass.
I am surprised that we have to do this sort of thing though. Surely the designers would have known that external GPS/Compass modules would typically have two cables (not one).
Does anyone know of an adaptor board or cable which would allow me to plug my external GPS/compass straight in without making changes like this, or soldering wires like @Terry Brooks?
Thanks for the info Andrew. Looks good so far.
Please continue to keep us updated on your progress.
Yeah After reading Jani's explanation I am not sure either about it's reliability.
Probably this much simplified APM-mini is not going to be very reliable. As Jani already mentioned, if the capacitors are not there, the ATMEGA 2560 is going to be very sensitive to any voltage spikes/drops or noise/interference and may brown out or reboot during the flight. I'm afraid of any crashing due to FC failure, looks like I'll stick to the large original APM 2.6, afterall it's not that big, without the case.
