Change 4x sst m3x8 bhcs to m3x10 bhcs for lcd board
Closed, ResolvedPublic


To add some extra grounding to the touchscreen, using 4x m3x10 sst bhcs will ground the display board to the conductive foam that sits behind the touchscreen display. The LCD back standoffs will need to be 0.5mm thicker so the screws wont bush too hard into the foam
