Are there specific and detailed instructions regarding connecting the Mega Pi to the Raspberry Pi boards together in terms of hardware and communication connectivity?
For the hardware part: would both boards have to be powered separately or can one board power the other?
For the communication part: how can we download programs from the raspberry Pi to the Mega Pi? What is needed to communicate with the Mega Pi board from the Raspberry board / OS?
There is not much on this topic anywhere really.
