Re: Pete Lomas's take on the compliance issues

In USA, Monoprice is infamous of selling high-quality low-priced cables.  I'm sure a bunch of people from USA would back up this statement.   This is not meant to be spam.

Is it safe to assume the I2C 1.8K pull-up resistor is installed on the final board, right?

Re: Berry Box - The Transparent Case

How tight is the vertical height inside the case?   If it isn't tall enough for me to plug a board on the GPIO (P1) connector and still be inside the box, then it is too short.

Oh, I didn't know the male headers were installed.  Various rumors have said the production boards would not have a GPIO connector installed.

Re: role of MS flooring in ESD safe areas

For ESD safety, everything must be connected between ESD surface and ground via a high-resistance resistor.  If metal sheets are connected directly to ground and high-voltage shorts to metal, then it can kill people.

Re: Should RPi have female sockets for GPIO like the Arduino?

<t>The Arduino Shields use "Female Sockets with 10.5mm tails" pointing downward, so the long pins can plug into the female sockets on the Arduino, yet still provide the female sockets on top of each shield to allow you to plug in more shields.<br/> <br/> I prefer having a Female Socket on the top si...

Re: Should RPi have female sockets for GPIO like the Arduino?

I think one of the reasons behind the Arduino success is the ability to stack multiple I/O cards on top of it.   I think Raspberry Pi Foundation is dropping the ball on this obvious design issue.  Even worse, they did not pick a default GPIO connector thus dividing the user community.
