Everything you need to plan a build
Sizes for your enclosure, power for your project, and how it all connects.
A 2 × 2 board with a 1 × 1 and a 2 × 1 module, top and side. Dimensions in mm.
Size and fit
Every board uses the grid in the drawing, so a board is exactly its columns × 50 mm and every module fits every board.
