2025-02-15 | pcb: J3: Add non-PoE 5V power input header | xengineering | |
Power over Ethernet (PoE) has the disadvantage that GND is significantly below earth. This requires that GND of a PoE-powered device is never attached to earthed devices. In production use cases this is no problem. The earth lines are isolated. Nevertheless for debugging it is sometimes useful to connect measuring equipment like logic analyzers and oscilloscopes to the board. This is not possible with PoE. Thus an alternative earth-based 5V power input is useful. | |||
