r1.2 board designs

Revision 1.2 board designs

This version makes mechanical improvements from r1.1 and adds PCB end panels to the design to replace the 3d printed ones

Notes with this release:
This design still has the coil whine with the default load resistor adding some additional load resistors solves this however.
The front end panel is a bit tight but this may be due to the accuracy of the milling from the PCB board manufacturer.

r1.1 board designs

Revision 1.1 board designs

Note: this board version has not been built and tested

This version fixes the electricial issues from r1.0 but the mechanicial issues remain.

• Output connector is not centered
• Cutouts for case screw bosses are too large
• No ground test point
• Connectors should be closer to case ends

r1.0 board designs

Revision 1.0 board designs

This version has several known issues.

• POE transformer output pinout is wrong
• Output connector is not centered
• cutouts for case screw bosses are too large
• no ground test point
• connectors should be closer to case ends
• pulldown resistor needed for bbuzzer channel
• load resistor required to maintain POE delivery
