General Info

Part Number: 10684

PCB Layout To-Do List

  1. Adjust the height of the PoE module to 1.02". The thickness of the PoE module is correct at 63 mils.
  2. The PoE module has components on the back that require additional clearance. Move the PoE module down the DSP board at least 200 mils to allow clearance on the top of the enclosure.
