Thanks Leonard
I took a few days to go over all the settings and make some improvements to the board for 18S, such as 3 additional capacitors on the output side. Now the inductance to the bulk caps is similar throughout the board. Although I am only adding them for people I know to be using 18S.

Also found the swdio and swclk pins the the debug connector are swapped which had me puling my hair out for a while!

I will be assembling all the V1.2 units and testing them (without explosions...) over the weekend. They should be shipped out next week if all goes well.

Can't wait to show you all how it looks now!
