Re: Consistent attitude offset in CF2.0

Yes, and as I mentioned in my original post, I rewrote the default eeprom settings using the write-eeprom.py script.

In any case, here's the config window:

Consistent attitude offset in CF2.0

Hey guys, I tried installing the bootloader and new firmware on one of the Crazyflie 2.0s and now i see a persistent bias in the attitude. The artificial horizon seems to reflect the manual tilting of the robot, but when kept on a level surface, the horizon shows the attitude bias again. Note that t...

CF2 Expansion Board incorrect pin representation

Hey guys, I think I found a discrepancy in the Rev.C schematic and the expansion pinout above. I think the UART2 Rx/TX lines are marked incorrectly in the expansion board. It should be USART2_TX. Also, N_IO_1 on the expansion board pinout should be: N_IO_2 Can you please confirm? Thanks! Expansion B...

Re: RFX2401C Schematic difference

And this is what the datasheet for the antenna suggests:
2450AT18B100E.JPG
So basically, the CF2 Rev.C doesn't match any of the suggested RF biasing :/

Any ideas, anyone?

RFX2401C Schematic difference

Hi all, The Crazyflie2.0 Rev.C schematic for the RF stage of the RFX2401C is significantly different from the suggested circuit. Does his affect the performance in any way? If not, on what basis was the C-L-L network chosen? Here's what the RFX2401C suggests: RFX2401C.JPG And here's what the crazyfl...

Crazyflie2.0 Rev.C vs Rev.D

Hello all,
Does any one know the difference between revisions C and D for the Crazyflie 2.0?

I see that though the project is advertised as open source, the schematics for Rev.D (available COTS) are not available on the wiki.
Is that true? Or am I missing something?

Thanks!

CF2.0 Hardware upgrade

Hello all,
I am designing a new robot and was wondering if there was any progress on releasing the updated kicad project?

It would be awesome if the new design can be binary compatible with the CF2.

Thanks!
