Single Board Computer (SBC) suggestion for interfacing with DMA

I am taking over a project where a Spartan 6 FPGA provides the interface between an ADC and a DDR2 memory chip. The FPGA takes 16-bit data out of the ADC and stores it into the RAM at a rate of 28MHz. I have the option of making the DDR2 controller…

Why is it important, in terms of ESD protection, to ground a PCB to its case (if not insulative)?

I have a 12V DC-powered SBC to mount inside a metal case. How important is it that I connect its ground(?) to the metal case on the interior? How is this going to protect against ESD events? From my understanding, whenever I touch the metal case,…

Why can't one use a Raspberry Pi (or any other computer) as a microcontroller?

Conceptually, I understand a microcontroller to be a very limited computer that can only run "one process". A microcontroller is what one would use when they want to interface with other electronics with strict timing requirements. This is because…
