I am still working on the soldered print board that I am going to use to attach the F3discovery to my quadcopter. So instead I used some balsa wood and female jumper wires to temporarily mount the board. Below is a video of my first flight in the park. This is with basic settings and I think there is a lot to improve but nevertheless it's looking good.

Thanks to lilvinz for all his hard work in this.

F3discovery maiden flight. (1 min 35 sec)

Yes, looking very good, congratz!

Do you have some pics of your wiring?
Hope you can make a shield/board soon to easily connect the F3D.
That'll help others trying to follow the project.

Lilvinz do you think f3 with 256kb's of flash will be too small for some Revo code features ...I'd really like RTH,loiter and waypoints on a plane...

It would be good to have more users for this board. I think it has a lot of potential. Apart from that it has a crazy low price.

The first picture is from my temporarily build balsa wood cradle. I connected everything with female jumper wires. I would definitely not recommend this for permanent usage but it was an easy way for me to discover the board and experience how flyable it was (and it's looking good ).

The second picture is of the empty PCB board and the connectors. I have made a lay-out of the pins that should be connected. http://www.lumivo.nl/temp/f3protoboard.pdf. This link is also in the wiki on the page of the F3 pinasignment.

The third picture is my board with the PWM inputs soldered to it. Unfortunately the solid core wire that I ordered seemed a bit to rigid for this job and the isolation of the white in the picture melts at a low temperature. Therefore it is taken more time for me than i anticipated on.


Seeing the results of my first flight I think I am going to order myself some PCB boards from oshpark or seeedstudio. That way there won't be any soldering the wires left. Maybe this is going to be interesting for more people?

Absolutely! Most users won't have a big problem soldering some pins.
But after seeing Vinz' first spaghetti board made me step back until someone comes up with a solution that even guys like me can handle.

PCB for STM32F3DISCOVERY


Hello,
Im on the way to build a PCB. I just build the Schematic and first place the parts.

Now I like to get suggestion what could be added or changed on the Board.

greetings

Hello Vinz,
is the I2C Bus with PA10(SDA) and PF6(SCL) correct?

regards

Hi robert,
this will be possible when the board is finished .
I started yesterday evening, please be patience

Isn’t this for the F4Discovery board?

I’m also drawing a PCB board in Eagle CAD for the F3Discovery. This is slow progress however because I have never worked with these kind of programs before. I will try to post my progress tonight when I get home.

No, it is PB6 SCL/PB7 SDA, see http://www.st.com/internet/com/TECHN...DM00063382.pdf

F4 Board is nearly the same. Only the connections are different.
I work with Eagle too.

I hope you move the 3-pin connector to the side, as they do not help you under the board
Also add a 5V voltage regulator and add pins that allow to connect a I2C sensor board, e.g. for a barometer. That could be placed below the CPU board.
You could also add some resistors for voltage deviders connected to free analog inputs for voltage and current measurement.
