The 5V regulator supplies power to the 3.3V regulator... if you are seeing 3.3V at the test point , then the 3.3V Regulator is OK. So it appears that the 5V regulator is shutting down ... for some reason... If you have a 7805 and are confident in swapping out the two parts , then it is a quick way t...

Yes , check the voltages first.. The 5V regulator is either bad or there is a short causing to much current draw , the regulator is shutting down , and then re-starting. Hence the blinking display... If it is good then the 3.3V regulator needs checked.. Also DO NOT grab the 5V regulator pcb when it ...

The fuse is OK , or the READY LED would not light.

My best guess is you damaged the 5V switching regulator ...This could be replaced by a 7805 linear regulator for testing , as this in Not a SMT part.

The Futaba jack and the JR jack share the same Trainer port, so there is only one input.

Well if your willing to go Class A-B , and you dont need headphone support
Then look at this guy

Very sad news indeed... Her incite and wit will truly be missed here.

change the battery , and try re soldering the chip , before you try to replace it

Digikey has a nice small 5V / 500mA DC-DC converter in a to220
945-1648-5-ND
Very small and priced very good..

5V / 1.5A
811-2782-ND

Here you go, There is a spot to add a 5V regulator by the user if needed.

You guys had Long lists to Santa Claus didnt you?

Maybe the 2 bottom holes ....cant make the board too wide..

Here is as close as it gets...

Here is how it is shaping up.. There is now a spot for a remote SD card and USB ports . On board RTC Battery. , and drive outputs for Haptic , LED , AUX.
Card is 3.5" x 2" , can be shaved down to just under 1.9"

The Gruvin Board sold for around $135 and the Sky board sold for $95.
Still interested?

Yon can solder a SMT tack switch to the PCB board , the silicone boot fits over the top of it.

I would have to make the board longer to fit a connector ... This is a full speed SD card interface , it uses 4 data lines , and needs a 10 pin connector.
I'll have a look....

Here is how the board is coming along..

I added a spot on the back to add some Open collector drivers .. for Haptic , LED backlight , and relay drive. There are solder pads
to access the required pins...

The USB signals are now brought out to a 5 pin header on the the 0.100" grid.

This LCD looks perfect for a 9x Shield ... or any other project ..
Having pins and not a FPC connector , means anybody could solder it in....

Thats a big difference....Digikey is not the cheapest ..thats for sure ...
North America is just too expensive to MFG this type of product ...
Thats why the whole thing needs to be made offshore...

-Brent

Yep , the 407 is priced better .. still expensive here ... the Canadian Dollar is way down against the US..
$1 CDN = $0.82 USD

The 100pcs price on the 1M part is $19.75 CDN - $26 single piece ..
The 100pcs price on the 512K part is $11.85 CDN - $16 single

A board like this has far more applications that it could be used on, Than a dedicated 9x board. The sky board cost way to much to make, dont forget the time to solder in all the through hole parts , program , and then test all the inputs and output functions..and because of the high part /track den...

The first shield developed would be for a 9X radio...

The schematic and board info would be released along with the Shield Pcb patterns. I cant release the pcb file , if I'm trying to get someone to Mfg a large run of boards (say 1000) There is roughly $25 CDN worth of parts on each board.. (strong US dollar ...puts up prices) Larger runs , would drop ...

I use a Head Loupe like this. http://www.amazon.co.uk/Rolson-Tools-60390-Loupe-Magnifier/dp/B001MJ0JW2#productDetails I find it works quite well , and does not interfere with your glasses (if you wear them) They have a wide field of view , and the different Lens allow for different detail work.. The...

The board could be shaved down to 1.9" but no smaller .. you just cant fan out the pins of the 100 pin ARM chip any smaller.
Putting parts on the other side will not change the width , and those parts have to be glued in place to pass through the oven..
-Brent

Yes, it would make a great project board....for just about any use... This ARM part has USB OTG ...which means that it can act as a USB HOST , so It would be possible to plug in a Joystick or Mouse for flight control....I think the DRONE guys will like that... With a PCB this small , you can easily ...

It would look something like this ...

Why would it not be DIY? It contains the core functions for a 9X style radio , but I'm trying to keep it as a general purpose Project board.. The idea is you make a Shield board to provide your exact requirements... There is no dedicated LCD interface, the connection provides for a 8 bit parallel , ...
