arduino_uno_r3_shield.rar by SalbaheJim

This is a blank shield board designed for Arduino Uno R3, ready for you to add your parts in Eagle CAD. The schematic includes custom headers with default power connections (+5V & GND). The PCB layout includes board dimensions, holes and headers already positioned and orientated. Look for the custom ARduino connector library I made (Arduino_JW.lbr) to simplify shield design. (This PCB should also be compatible with Arduino Leonardo, Due, Yun and Mega.)
