What version of KiCAD are you using?
Thank you,
Andy.

Re: Guepard board
I'm using Kicad(2013-05-16 BZR 4016)
I have change my schematics for MPX4250, because I have used the wrong footprint like you say
github is now update

Re: Guepard board
I realize this board this week to proceed some test.
Can you say me if I need realize some modification or can I test like that ?

I don't have time to check it over, but if you hold off until Dan and/or Andy have had a poke around, that would be a good idea.flat4power wrote:Can you tell me if I need to make some changes or if can I test it as it is ? < best

Re: Guepard board
thanks for the lesson
I will try to do better next time
I will try to do better next time
I entrust the implementation of the pcb because I do not have the resources to doAre you going to etch it at home yourself?
Ok, I'll wait a little to have a feedback from Dan and/or AndyI don't have time to check it over, but if you hold off until Dan and/or Andy have had a poke around, that would be a good idea.
Re: Guepard board
In that case, the correct form would be:
I will have this board made this week to do some testing.
or
I will get this board made this week to do some testing.
or
I will have this board manufactured this week to do some testing.
:-)

or

I will have this board manufactured this week to do some testing.

Re: Guepard board
Matthieu,
After reviewing your PCB layout in KiCAD, I have found the following areas you will want to correct before having boards manufactured:
1. Take a look at where you feed power into your decoupling capacitors for the MCU, you need to feed the power into the polarized tantalum capacitors then route to the ceramic capacitors before finally routing to the MCU pins. Specifically power into C47, then to C2, then to the MCU pin. Same scenario for C48 and C3.
2. C4 and C44 shouldn't be in parallel, C4 should go to one pin of the MCU, the C44 to the MCU pin next to the one C4 is connected to. Here again make sure to feed power to the capacitor before routing into the MCU pin.
3. The RPM-Crank-IN+ and RPM-Crank-IN- traces in the corner under U11 are close together, try to keep them the same distance apart in the 45degree angle traces as you did before and after the 45degree angle.
4. The ground plane under the Freescale MCU should look like the suggested PCB design in the Freescale 9S12XDP512 datasheet. If you open up my Jaguar 0.4-alpha board layout in KiCAD you will see the correct shape it is to look like.
Once you get those corrected I can take another look to make sure there are no other issues.
Thank you,
Andy

I worked on changes
Github is updated
Thanks

Re: Guepard board
In my schematics I have this for bluetooth communication (3.3V module)
But is it possible using ADUMX201 (like on USB communication) as an level converter between MCU 5V and bluetooth 3.3V.
thanks for your help
