This model is created for people using raspberry pi to learn hardware electronics. This model will make your work neat and good looking and easy for implementing test circuits. 

Additional things:

• M3 Nut x 4nos
• M3 10mm Stand-off (Plastic or Metal)
• M3 Screw x 4nos (4mm) - (for mounting raspberry pi)
• M2 Screw x 2nos (8mm) - (for mounting limit switch)

This project was one of my assignments, which uses raspberry pi  and ADC. As I want to make my prototype, good , neat and easy accessible. 

I hope this model help you.  Please share your feedback
