My name is Shadeed Mahmud and I had query about raspberry pi extension boards.
- Can you double stack these extension boards? (http://au.element14.com/piface/piface-digital-2/i-o-expansion-board-for-raspberry/dp/2434230)
For example I need multiple different modules mounted on the raspberry pi board. So I'm thinking of mounting an extension board to the GPIO pins and have these pins extended then I will mount another extension board on top of the previous extension board. Is that possible?
- Also these boards have 2 relays in them, I need 8 relays, does element14 have any thing like that? I looked into other options such as this ( UniPiUnipi Board for Raspberry Pi ). Does element14 have anything similar to this or can they procure such a board?
Please get back to me at your earliest convenience.
