OSD based on STM32F4

Bummer. Might not be down to just your your PCB though.

Note the clock frequency or bitblasting timers can run at harmonic of the gps etc.

also consider.. uhf and 2.4 control frequnecies.

nightmare isn't it!

Not on your own - my DragonOSD kills my UHF range unless get good separation. Moved antenna and 6* increase in range...
also Ambaralla chipset on some GoPros runs 216mhz - harmonic of 432. Right on edge of 433 control :) great huh.

Unlucky Andy. Hope your spec an works ok and you can get it sorted.

Brucey · March 05, 2015, 06:49:17 PM

That's odd. But like you say, better to get the design sorted now rather than trying to fix it later

Well that really confused me, a quad, in the snow?! Then I realised it was one of your fans! Nice one

That looks tidy Andy. Good news on getting it fixed, you must be pleased.
Let us know when your planning on testing it.

It's looking good - although the compass to me looks a bit busy with the 2 hands in there. If you want a compass on the bottom like that, then what about just having an H floating on the outline of the circle so you could get rid of one of the hands ?

Of course there are loads of ways to represent direction and home as well, I don't tend to think about which compass direction I'm flying in, but favour more which way is back home

I'll bring my RFExplorer with me when we meet up on Sunday Andy, we can then give the fella' an RF checkup.

Up to 2.6 then 5.something to 6G.

Edit, found the proper spec:

Frequency band: 15-2700 MHz and 4850-6100MHz

Gundummy · May 11, 2015, 11:20:11 AM

thats a really nice little feature to have

Brucey · May 11, 2015, 12:41:36 PM

Cool, like the lidar. Would it work forward facing to detect fast approaching goal posts?!

Brucey · May 11, 2015, 01:55:56 PM

Cool, looks like it was backing away a bit too much! Into the neighbours house!

Brucey · June 28, 2015, 10:39:09 PM

Yup, compass is much better. Good work!

You have to be minimally computer literate though :o

Which thought we all were these days!

"computer literate" - I thought I was - which makes it even worse for me !!

No programming required whatsoever!

I'm not worried about that, I need no soldering required whatsoever!
