A master list of plugin “shields” for the Arduino family. Everything from display shields, ethernet, wifi, even sound and data logging. Over 100 and still increasing. Check it out!
Sick of trying to figure out which pins are used by some obscure Arduinoshield? Can’t tell whether two shields will be compatible with each other?
This shield database arose out of a discussion on the Arduino Forums about the need for a comprehensive online reference for shield pin assignments. It lists as many Arduino shields as I can find along with their pin usage, making it easy for you to determine if particular shields are compatible.
