It is really hard to find out what is in the current release.  Is there a release history?Just trying to find out if the LED_Mode has been added to ths Plane firmware yet?Last comment on this was in 2013 so I would have assumed this had been…

John mallett replied to Assaf Weiss's discussion How do I arm APM?
"I think that the entire concept of ARMing should be the same as the Quads.
I nearly got hit by the prop on my plane as I connected everything up including the external leds.
This is really very important.
Any idea how soon arming and Ext Leds will…"

John mallett replied to Stefan Gofferje's discussion ArduPlane external LEDs and beeper
"I have found that the arduplane software needs a few things:
Led status so that you can see what is going on with GPS and Armed or not?
It does not seem to have the same arming procedure as copter??  Mine just arms all by itself!! Nasty.
Any idea if…"

John mallett replied to Graham Dyer's discussion Strange external compass issue, APM 'sees' it but mostly doesn't...
"Hi,
I have bought a non 3dr compass module said to be hmc5883L but I notice it dies not have the 'translator' fitted to the 3dr module?   I hope this will work direct into the I2C port on the APM.

What does the translator do?

Or do we have to use…"

John mallett replied to danne's discussion Connect USB and power module at the same time?
"Ok,
This is the failure mode I have researched.
1.  I connected an SBEC to my rx and powered the APM from the rx leads.
2.  I connected the USB lead to my Laptop.
3.  It initially connected ok
4.  I had a wiff of burning and the Usb connector was…"

John mallett replied to R. D. Starwalt's discussion APM2.5 5V/Vcc Schematic
"Ok Philip,

So it is just called 2.6 because it has no mag chip?
The board is really a 2.5 not 2.5.2 (for which I have the Eagle files)
Confusing eh?
Big chages in the board from 2.5 to 2.5.2.
Thanks for this really critical clarification.
All the…"

"Craig,

I have about 20years experience looking at CAD and multilayer PCBs.
Not sure why you feel that 2.5 is the same as 2.6?

Look at the 2.6 board.
Above U3 the 3.3v regulator (APM2.5)
U$15 Has changed chip??
2.5 chip is not as big as the 2.6…"

"Not on the APM 2.6 it will die!!!
Mine did.

But I had an SBEC feeding the RX and RX connected to the APM 2.6.

Seems it is different to the APM 2.5 because I have seen a video on YouTube that shows exactly what I did and it worked fine??

John mallett replied to danne's discussion Connect USB and power module at the same time?
"The APM 2.6  I bought (3DR) died when I had an SBEC providing 5.2V to the RX and with the RX connected to the APM.
As soon as I plugged the USB in it fried the two components next to the USB and seems to have taken out the 3.3V.
 
As for the PM??? …"

John mallett replied to R. D. Starwalt's discussion APM2.5 5V/Vcc Schematic
"Hi,

Took a look at the Eagle file and they are the wrong ones.  Not close to the 2.6?
These files are APM2.5.2. The chip layout of the APM2.6 is different.  And so is the chip numbering.
Got the ratsnest sorted (I am used to CAD systems).
 
Any…"

Wrong board - This link is for the APM2.5.2 Eagle files.  Where are the 2.6 ones?

"Philip,
Just had it on the bench (anti static and solder station)  connected the RX to set modes rx is powered by and SBEC. 
Plugged in the USB and used mission planner to connect - no problem.
You know you are very sensitive to hot components so I…"

"Doug,

Thanks for that info.  Where did you get the APM2.6 Eagle files from?
I am trying to find a way to repair the APM by providing a bypass of the blown track.
I also notice that the first two sensor ports labelled SPI are in fact two ports?

"Well I am used to using the other Arduino boards,  I use the 2560 mega R3 which is nearly the same size as the APM to control my observatory power and humidity etc.
That board runs from a 12volt supply and I also have a USB plugged into it.  It does…"
