Feather Mounting Hardware
The mounting plate for the Feather has four standoffs with M2.5 mounting holes. These line up with the mounting holes on the Feather. Place the PCB over the mounting plate and line up the mounting holes. Use four M2.5 x 5mm flat head metric machine screws to secure the PCB to the mounting plate.
Flat head screws feature a chamfered edge. Pan head screws (sometimes called button heads) have flat surfaces that require adequate space. The mounting holes on the Feather PCB have very little spacing so a flat head screw is ideal. If a pan head screw is used, it will cover up components like the chip LEDs. We suggest using a M2.5 tapping tool to create threads in the mounting plate.
