Hardware
There are two parts of the hardware. The pcb and the housing of the PMG
. The pcb is created with KiCAD
and the housing with FreeCAD
. All files are built with github actions
so that they are ready for a production environment. The housing is printed with a 3D-printer (Dremel 3D40
).
PCB
The circuit board is populated on one side (Top). The best way for soldering is within a standard soldering system.

Mechanical
The housing has a tolerance of 0.2mm
on each side of the case. So the pcb should fit perfectly in the housing. The tolerance can be modified with FreeCAD
in the Parameter
Spreadsheet.
