I am designing a driver board the same size and with the same mounting holes as the Q8 driver for the lantern project. I need some size dimensions for the PCB including
1. board diameter
2. center to center hole spacing for the two mounting holes
3. mounting hole diameter
4. dimension for for the shelf on which the PCB rests so as to keep parts out of this area with some margin.
5. centerline diameter of the positive battery ring trace.
I appreciate any help you can provide, thanks!!
