We completely redesigned the protoshield for Arduino
Larger size, matches the Arduino UNO R3 board size
New pinout compatible with R3 boards
Compatible also with older boards (Arduino UNO R2, Arduino Duemilanove, Diecimila, Freeduino)
PADS don't touch the Arduino USB connector, so more tapes on Arduino boards!
Central GND bus
Central VCC bus (5V - 3.3V selectable)
SOIC-8 SMD component area
General purpose switch area
4-pin terminal block area (fits 2.54mm terminal blocks)
Holes matching the ones on the Arduino UNO board
ic2 area
16-pin DIP IC area
reset switch area
All headers matches 100% the position of the Arduino UNO board
Black soldermask!!!
