Any hardware expert here?

Raspberry is a Linux based system that has CPU, RAM (SDRAM chip) and some more items. Generally speaking , to be able to start successfully CPU and RAM must ( also )work properly. If CPU or RAM is faulty, Raspberry does not start. Let's suppose that Raspberry did not start and only either CPU or RAM...

Re: ARM2835 pin assignment

Thank you for the reply. And is there any modification necessary to be made if I want to use JTAG?
E.g. any strap pin, pull down/up resistors or similar?

Re: infrared v.s. normal camera

I expected the normal camera will work during the day but infrared camera will work both at night and during a day too (as a surveillance camera)
Is it true or not?

Re: How to play a recorded message

Thanks for the reply.
I think that the 3.5mm headphone socket has a low amplifing power( low output).
So I would need probably to use HDMI sound output. But is there any way how to use HDMI with a speaker only?Not with TV ?
