Grounding protects the components from the static electricity that can be naturally present (electrostatic discharge, ESD).
Notice: Risk of damage to the equipment due to electrostatic discharge. Always: Touch the working surface before touching electronics.
Ideally: Use ESD protective equipment, such as ESD table mats and grounding cords.
Insert an M2.5 screw upward through the bottom mounting hole on the X1500/X1501.
Thread an M2.5×12mm female-female spacer onto the screw from above and tighten it by hand until finger-tight.
Plugs the POE HAT directly into the IO board's GPIO and PoE pin headers.
Secure the POE HAT to the spacers with two M2.5x5mm screws.
