Modular frame to help you with your DIY arduino/electronic projects. So far modules allow you to mount Arduino mega,Arduino Uno (and probably clones of these boards, but i can't guarantee they'll fit), prototyping boards, prototyping PCBs, lm2596 buck converters. More modules might come in future, depending on what I work on.

The author marked this model as their own original creation.
