Switch TVS diodes for uC-connected I/Os and rst_n to 3.3V from the (accidental) 24V used. Change 12V fuse to the (correct) 4A component, now that we have the part in the library. Change the 18V zener for a better-sourced component.

The anchor point in such connectors is the geometric center, here the first pin was used. This caused the component to be misplaced in eurocircuits' pick-and-place check tool.

- replaced AD8029/8030 with OPA192/2192; the absolute maximum voltage was only 12.6V (12V + 5%). The OPAx192 has a maximum voltage of 36V. - replaced the USB protection diodes with the right part, PESD5V2S2UT.

- replace IRFH5025PbF with IPD5N25S3-430 due to lower Vth shift - add test points in various places - add ceramic capacitors to MOSFETs and fans - add some labels/groups to indicated which connector is for what - reversed polarity of ESD protection on USB lines - add 32kHz crystal in parallel with 8MHz - add one more bypass cap to the uC - replace main connector part - show the power input/output voltage levels in the main sheet - the low side of temp. monitor connections is fixed to ground, make that more obvious

- connect "rst_n" line to "EN" input of IC2 to fully power-cycle uC instead of just resetting - remove 0.1% resistors - optimize resistor values - use just one type of 10UF capacitor - optimize capacitor values - use larger bypass caps for the MOSFETs - use a schottky instead of the ultrafast ES2A - add 10ohm current limiting resistors at the gate drivers - add a fast zener at the gates

- CERN OHL: "Copyright 2019-2020" - 2.49k instead of 2.55k for the PT100 current drivers - to avoid copy&paste mistakes, a single temperature measurement channel could be placed in a separate sheet and just instantiated 3x in analog sheet - to avoid copy&paste mistakes, have 1 sheet with single fan channel and instantiate it multiple times even on the main sheet.
