XRacer F303 FC V2 - New version
#61
I finally solder my New and first build !  
So I eventually tested your advice,  you have some serious guts oscar !  You were right,  and only you made That guess !

So i made a video of the fc : https://youtu.be/doXNHEOvx3M?t=141s

We can see ne respond on normal and boot mod when only connected by usb,  but it revive when iplugged in the +5v rail (where the vidéo link start) 

So what does That mean ?  Is it Still operational ? Can i still flash it ? 

I didnt went fruther than checking gyro and direction of motors spinning. 

Thanks for your time oscar

So it worked,  my f303 is on cf 1.13 but i cant put it in bootloader mod. 

I received à New f303 v2.1 fro fpv model,  thanks to them !  But i tried to change the driver of stm32 when connected on boot mod but zadig wont recognaze it as stm32,  only uart to usb driver appear 

Edit: I raid your review again with New eyes.  I didn't remember you spotted this problem of 5v usb diode burnt. It seems That I have same problem with this v2.1.  

Do you think it is OK to use it like that ?  Can i still flash it ?  Should i try to flash the New one ?

So i'm Still working on my first v2.1.
I have a pb with my received, now its OK i Will fly this week end... Finally !
I flashed BF 3.0 rc12, seems OK.
I have to calibrage my esc now (xm30a, blheli14. 4)
But i cant as with my dead diode, fc has to be powered by the 5v rail.
Do you know an other way to calibrate esc ? The process wont start on BF if powered from Antoine elles than usb...

Thanks

I think you can just set PPM min/max manually on the ESC as a last resort.
Have you tried contacting FPVModel about your issue? see if they can help? http://intofpv.com/forum-fpvmodel

Yes i had, they send me an other fc last month. But as I managed (thanks to you) to start the first / burned diode fc I mounted it on my model...

Really great Customer support at fpv model !

But i dont like to waste so i try to get all i an from this fc Smile

Did you get any desync with BF 3.0 ans BLheli ? Has i inverted 2 of my redbottom by the blhelisuite, I'm am afraid of these dead loops That happen to a lot of pilots
I use xm30a (old big capacitor version) on bhl 14.4.

I got an idea: can I pass trough UART 1 or 2 to connect it on BF ? Will it be powered by 5v from it ? What i have to check before to do it ?

I manage to calibrate trough UART.
It works fine on BF3.0 R12 .
try it today , it was a blast.

Thanks again oscar for your support

Folks,
as I've posted in another topic recently the soldering pad for buzzer got ripped off last day. I was told to try scratching the board to be able to solder a thin wire to it or solder directly to the FC but I don't think I could do that. Smile
Do you know if it's possible to remap the pins on the board somehow? Can I set up for example one of the unused motor outputs to behave as a buzzer pin?
Thanks!

Or should I run telemetry on SoftSerial (like on Naze32) but I can't find which pins are used for SoftSerial in X-Racer F303 Manual. Does anyone know?
SmartPort telemetry runs on a higher baud rate than recommended for SoftSerial though so it will tax the CPU a bit..will I still be able to run 4k refresh rate on the FC ( or 3.8k as Oscar recommends in his recent article) ?


Has finally somebody managed the Softserial  to work  with Smartport telemetry?

I would like to replace my old Naze32 v6 with a F303 3.1 but I am concerned about my  X4RSB telemetry.
I am used to make a softserial with 2 pins on Naze32 and telemetry is OK, but I am reading post about problems finding the rights pins on F303, or even baud rate problems etc.

Which is the smartest way to manage this?

I have seen people using UART1 (USB shared) and  then disconnecting the X4RSB when usb connection is needed.  Why are not they using UART2 for telemetry??

In my case I only need SBUS  (UART3) and  Smartport Telemetry (... Smartport? UART2? )


Thanks!!

What fc version do you have?

You can connect it to uart1 and still use usb, but the telemetry will only work when the quad is armed, so you'll have to search for new sensors while armed. You could probably use uart2, but there has been some RX/tx mix-up with v3.0 if I remember correctly. I have it connected to uart1, as my osd is on uart2
