# Arduino Uno R3 Shield Template ## Description Template for Arduino Uno R3 Shield. Include an official pinout so you will always know Arduino names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Arduino Uno R3 itself along with the board outline on the silkscreen. #Arduino #Uno #Shield #Template #project-template #project ## Project Details -
