AIO pro/ GPS??

[Royston]

Hi Guys
Eventually got board working with UBEC. Loaded firmware etc.
Everything sound except no power to CN 06 GPS.
Any help, as always, much appreciated.
Regards
Roy

have you got it wired in correct??

[Royston]

As far as I can see. Serial port and looks same as 450  Peter King one I';ve got??

[fruitsalad]

check for any dry joints on the pads,and all wires are crimped properly..
you never know....

[AM556]

Is Peter';s GPS powered from the serial or as mine, pin 11 of the ESC? If so, have you got it connecting to the same pins?
I don';t know why his has a red still connected to pin 2 of the ESC row while the jumper is removed and board powered via a ubec?

[Royston]

Peters is through serial port. Connects the same. My ECSs are opto and board powered by ubec. All ESC wires are still connected???

[Royston]

Think I';ll try cable off 450. At least that will eliminate that from the equation.

[Royston]

OK even more confused now. Tried cable off 450 which is a actually a Hextronik. GPS lit up green but no indication on the board. Tried Hexatronic complete and fine ie. green light on board.
Also board only boots up when USB is connected.
Anybody any ideas where I go from here.

I suffered similar thing with my AIOP board once when it would only power with the USB when I changed firmware.

I reflashed with the working firmware version from here and everything was fine.

Worth a shot rather than pulling your hair out?

[Royston]

Cheers.  Will give it a go.
Any ideas about gps

Peter does demonstrate needing to "jump start" the board when using USB by connecting a battery, though I';ve not needed to.
When you use the cable only from your 450, is the TX from one going to the RX on the other?

[Royston]

Hi
The board won';t boot up at all unless its connected to laptop via usb.
When using cable from 450 nothing shows on board just a green, I presume power light, on crius gps unit but no light on board. Is that what you mean??

[AM556]

"Eventually got board working with UBEC" Are you sure? "The board won';t boot up at all unless its connected to laptop via usb"

[Royston]

Yep
Just tried again to make sure I wasn';t mistaken.
Power up with lipo nothing. Plug usb into laptop and hey presto it boots up. Its got me??
Quad will arm/motors turn. As soon as I unplug from laptop board dies.

If you fit your jumper and power with a Esc does the board power then ? did I read earlier you may have connected your Ubec in reverse I wonder if you have blown something on the power input side ?

[Royston]

Hi Gaza
Re-fitted jumper but no go but ESCs are OPTO??

[Royston]

Meant to say no ubec not reversed but during process of wiring board poss touched + - 5v input pins with a live feed.
Will that mean that board is G********SED??

[Gaza07]

Ah opto esc';s dont have the bec erm you could try the ubec connected to the + and - esc pins on the board see if it gets power from there, if it does then I suspect you have popped summat on the extended power port, make sure your ubec is set to 5v though 

[AM556]

Have you removed the yellow jumper?
Is your UBEC connected to the yellow pins to the right of where you connected the receiver?

[Royston]

Hi Gaza. UBEC is 5v. There is power to the board from UBEC. Tested with voltmeter. Do you mean to move UBEC connector from where it should be to where one of the ESC connectors go??

AM566, sorry don';t know your name but yes have removed jumper and it is connected to yellow pins.

Have horrible feeling new board coming up.

[Royston]

On a more positive note. After a close inspection of GPS wiring and your AIO manual i don';t think It was wired quite right so will give that another go tomorrow.
Thanks Guys

[AM556]

Sorry Roy, I';m Rob. You could plug the UBEC into one of the ESC ports and replace the jumper.
If that works, I';ll check with my microscope tomorrow to see where the diode will be that may have popped.

[Royston]

Cheers Rob
Tried ubec on ESC pins but unfortunately no joy.
BUMMER
 

[AM556]

Hmmmm  I';ll assume you';re certain the polarity is correct. Do you have another 5v supply you could cannibalise to power the extended pins? Things are not looking good 

[Royston]

Yep Rob polarity OK. Unfortunately don';t have any other 5v supply. But you';re right. Not looking good.  Oh well RC Timer owe me a credit as ESCs were supposed to incorporate a BEC

To get power to the Serial port of the AIO Pro you will need to power the board via the Ext power port using a UBec or the power line from one of the ESC';s Bec';s.
If you just power the board from the ESC';s BEc on the motor rail then you will need to connect the power pins of the GPS to the motor rail and not the Serial port.

Also make sure you are using UBlox in your firmware for GPS type, if not then just try one of my firmwares:
For firmware settings and information files please see my public Google Docs folder:

Make sure GPS is connected to Serial pins Tx2 & Rx2.

Remove the jumper (middle of the motor rail) when powering your board from the Ext power connector.
