From 60369177e1e9ad171d600d40e8438430e154e558 Mon Sep 17 00:00:00 2001 From: xengineering Date: Sat, 15 Feb 2025 22:02:25 +0100 Subject: pcb: J3: Add non-PoE 5V power input header 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. --- pcb/power.kicad_sch | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'pcb/power.kicad_sch') diff --git a/pcb/power.kicad_sch b/pcb/power.kicad_sch index d4c47db..2fc67a5 100644 --- a/pcb/power.kicad_sch +++ b/pcb/power.kicad_sch @@ -5,4 +5,26 @@ (uuid "04efbab4-4b09-41dd-b889-e48452d150e7") (paper "A4") (lib_symbols) + (hierarchical_label "EXT_GND" + (shape input) + (at 50.8 116.84 180) + (effects + (font + (size 1.27 1.27) + ) + (justify right) + ) + (uuid "63f6c991-7d4d-49ef-849f-23837f200404") + ) + (hierarchical_label "EXT_5V" + (shape input) + (at 50.8 114.3 180) + (effects + (font + (size 1.27 1.27) + ) + (justify right) + ) + (uuid "f4c611bb-4ee4-414a-8506-b9578937609d") + ) ) -- cgit v1.2.3-70-g09d2
