[Allwize] Bad connection between boards

[arcediano90]

J10 & J11 touch the HDMI connector when the connector J14 is connected to Raspberry

Options to solve this:

• Moving the Arduino headers further from the RPi header: it won't work since the user won't be able to plug the HDMI cable.
• Placing the RPi header "at the back" of the board, rotated 90 degrees: it could be a better fit, but still the Arduino headers will touch some components in the Raspberry Pi
• Do not populate the headers by default: problem is that main target will be the Arduino users so most people will have to solder them themselves.
• Using longer headers: could work, soldering the tips of the header pins at a certain high (we need minimum 5mm more than now). The header should be soldered so it sits flat when mounted over an arduino. See pic.

So last option looks like the best at the moment.

Since we are not adding the Raspberry Pi header in Rev PB this is no longer required atm.
