Constructors should refer to the Component Overlays along with,
the PCB Bill of Materials for the current value of all components, and
the General Construction Notes for general PCB assembly guidelines.
Start by assembling the Lower PCB.
Fit all components except for the extended receptacles J2, J6, J7, J8.
Then assemble the Upper PCB.
Mount the receptacles on the Lower PCB but do not solder.
Mount the Upper PCB assembly, if you have 2 spare M3x6mm bolts then use them to temporarily hold the Upper PCB assembly to the Lower PCB assembly.
Solder the receptacles.
