Re: Can RaspPi power Arduino?

Sure about that?

USB means 5V to the Arduino, so serial will be at 5V TTL level. From Arduino to RPi it would be safer to use a level shifter.

Re: Raspberry B+ - no HDMI Signal

If nothing connected but the power supply to the micro USB and no LED on the RPi lights up?

1 usb cable is broken
2 power supply is broken
3 RPI is broken

Since you switched the power already it has be 2 or 3.

Can you measure the power pin on the RPi?

Re: Can RaspPi power Arduino?

The short answer: yes, the +5V is enough for a simple Arduino Uno or so.

The longer answer: what do you plan to do with the Arduino? Some shields can require more power than available. So calculate!

- If also a border, then you might adjust the VGA monitor via its OSD menu for adjustments if any.
- If not, try the overscan settings indeed.

No solution so for the B+ in an easy way atm. For a RPi B is it possible to go back to an older kernel version with ease.

Re: model B+ is not working with 3.10.25+ kernel

1. Integrate the better driver yourself in the kernel (quite a job to be honest)
2. Wait for the betetr driver to appear in the 'next' RPi kernel. It is in the Debian development streams somewhere IIRC.
3. Get a RPi B instead of a B+.
