Thanks, guys.
Max,
I will send you one of these updated versions. I moved some things slightly to make room for standoffs and add the M2 pressnuts to secure the M4 to the expander. So its now a perfect fit for a Leora or any other Nanowii based frame. You are gonna love it and I worked out pretty good PID´s for it too.
Joerg,
It works nicely with the Brass M2 inserts. I stack a bunch of washers onto the screw that holds it in place to keep either of the boards from warping and both lined up to each other. Later there will be a plastic spacer, but with china on vacation its gonna take a while before they get here....
Of course it wouldnt be right if everything was right. So these production prototypes was made on 1mm PCB by manufactorers error. It makes it a little tricky to solder the servo connectors when the board was designed to be 1.6mm.
I also swapped the Silkscreen marking for M7 and M8
. But its all cosmetic and the boards are working just fine, so I will make them available instead of waiting 4-6 weeks for a new run to be completed.
