Medium Size Breadboard

This is a medium sized breadboard with around 320 tie points. It's 2.2" x 3.4" (5.5 cm x 8.5 cm) with two power rails on both sides.

These boards can clip together in 2 dimensions to make bigger breadboards. The power rails can be easily detached for a thinner board, and the groove in the middle makes it easy to cut the boards in half to make really tiny breadboards.
