So slightly annoyed now.. the dualtos boards are missing the 2 inner layers :evil: So its going to push back this project again as I can't test the new boards now :(

EDIT:

I will try and hard wire the missing layers.. The via's are there.. I used copper fill on top layer connected to 0V so hopefully that will be enough to get a board working.

EDIT2:

Now working!

Made a start on the (hopefully) last revision of the booster...

Looking good to me.

C1 is a little wonky though :P :lol:

I charge more for unique items like that ;)

About the same as C3 ;)

Am I seeing things, or does the new dual TOS board only use 8 pins of the HI socket now? In other words just the data lines and GND?

I think the SMT pads are to big for the parts.. that's what happens when you cut corners as use "built in libs" :roll: :lol:

Not seeing things no.. I've moved the SMT socket there so pins had to go.

:bravo:

PCBs on order, so a waiting game next :) :ball:

I've got 2 more PCBs here, so will order parts next week , see if I can build them up as pre-release boards :)
