MEGAshield KIT for Arduino MEGA 2560 R3
The MEGAshield for Arduino MEGA 2560 R3 is a shield that sits on top of the Arduino board and allows you to create your own shield.  Is like using the breadboard for prototyping, but making the project more permanent.  It is very useful when you create a prototype and then you want to make it pseudo permanent and sit reliably on top of the Arduino board.KIT requires assembly and solderingIncludes:  PCB, 1 2x18-pin female header, 1 10-pin female header, 5 8-pin female header, 1 6-pin female header, 1 2x3 female header2 tactile switches, 1 3-pin male header, 1 jumper.To assemble the MEGAshield for an Arduino MEGA 2560 R3 board, use 1 2x18-pin female  header, 1 10-pin female header, 5 8-pin female header, 1 2x3 female header, 2 switches, 1 3-pin male header and 1 jumper.  After assembling the board, 1 6-pin female header will be left unused.To assemble the MEGAshield for Arduino MEGA 2560 R2 or older boards (Arduino MEGA 2560 R2, Arduino MEGA 2560, Arduino MEGA, Arduino MEGA ADK), use 1 2x18-pin female header, 5 8-pin female headers, 1 6-pin female headers, 1 2x3 female header, 1 3-pin male header, 1 jumper and 2 tactile switches.  After assembling the board, 1 10-pin female header will be left unused.
