what is a "Shield"?
I am completely new to the Raspberry Pi and have seen references to boards called a shield. What is a shield?
Re: Shield
The term seems to be an import from Arduino-land where add-on boards are called shields. I don't know the reason.Mooncarrot wrote:I am completely new to the Raspberry Pi and have seen references to boards called a shield. What is a shield?

Re: Shield
A Shield is an expansion board that fits on top of an Arduino microcontroller board.
This is a typical Arduino shield (for a seven segment display)
A "HAT" (Hardware Attached on Top) board is the nearest equivalent for the Raspberry PI B+.
This is one of the first HAT boards, a HiFi audio card.
more info about HATs here:

Re: Shield
...and other microcontroller boards have add-ons named "capes" and "wings"
