Re: Making a custom 'motherboard'

Check this out:http://www.hasseb.fi/pi
You can find the schematics and Eagle cad files for a custom motherboard from the link. I think that's a good starting point.

Re: CM Custom PCB power problem?

Still it sounds like a powering issue. I think it is not very good idea to use a single 3.3V power supply for VBAT and 3V3. Is you supply strong enough to provide at least 3 watts of constant power?

Re: CM Custom PCB power problem?

Should you have some 5 volts input for your CM? Pins 197, 198, 199, 200?

Re: Aluminium enclosure with display

Thx. If everything is included, your price is good. But then, why the big red message "NOT INCLUDED" on the pictures? I usually suspect some marketing trickery there, if I see something like that :lol: Looking at the site today 13/02 The PiTFT is not included. The photos show two different displays...

Re: Aluminium enclosure with display

Thanks for the correct link. The 20x4 character display is included into the price. You can buy the TFT display from Adafruit, the price is roughly $50.

Re: Audio output

Thank you very much and merry christmas, audio works now. I should have asked before, I spend something like two weeks and plenty of euros trying to find out what's wrong. By the way, how does the kernel knows which revision of the board I'm using? At least there are no pull-up or -down resistors to...

Audio output

I have a problem with the analog PWM audio output. I can not get audio signal out from the GPIO pins 40 or 45. The connection is similar to the Raspberry Pi and the schematics can be found from the attachment. What have I done: 1. Tested the R-Pi Troubleshooting: http://elinux.org/R-Pi_Troubleshooti...
