Reverted GND plane thermal reliefs

Everyone gets thermal reliefs... you get thermal reliefs, YOU GET THERMAL RELIEFS !

Housekeeping update - 1.2.2

Version numbers updated to 1.2.2 for the schematic and PCB
Components identified, datasheet and descriptions updated
iBOM regenerated
PCB plots regenerated
PCB :
- only thermal reliefs on PTH, not on SMD pads
- couple GND islands taken care of
- couple rationalisations on the 3v3 rails

GND fill thermal reliefs

Changed the GND plane fill to thermal relief to aid manufacture

PCB update

Includes 12V switcher updates plus other tweaks and additional ground stitching

Updated 12V to 3V3

Simplified 12V to 3V3 switcher

Comments

@Alex-XNR
Just confirmed with comments to educate me.
I think the only point that remains open is the question of Rf and Ri ? I can't remember where I saw they were included and I can't see, to find anymore.
For the higher resistance I/O I think I will try with a higher Iset resistor ? With my crappy simulator it seems to run.
