Mechanical Prototype Board - A5 Sized (MPB2-A5)

The MPB2-A5 Mechanical Prototyping Board is a board for prototyping electronic circuits where components require mechanical attachment rather than just soldering to perf board. With slots designed to fit M2 screws, this A5-sized board allows for easy mounting of individual circuit boards, and other components, using screws, nuts, and standoffs. The board also features corner holes for mounting to other fixtures using M3 screws.

If a circuit board’s mount holes won’t align with the slot pattern, custom cradles can be created to secure them to the MPB2-A5. Over time, a catalogue of cradles can be created for commonly used components (for example, different Arduino boards, motors, buzzers, batteries etc.), making it easier for everyone to create prototypes.

A5 is the largest size created so far as it will still fit onto most FDM print beds:
