I only made a small change because I received a discount code from Eurocircuits and I thought let's try that out. I only moved the TPL5110 circuit to the side to make space for any circuit that an user may want to add. I did not even assemble the PCB. 

What I've learned

• Eurocircuits is fast, they deliver in 3 business days
• PCB thickness any other than 1.6mm don't fit in the pooling batch and are very expensive and so the board is 1.6mm in stead of the desired 0.6mm.
• 1.6mm is too thick for my application. It add unneeded weight. I need 0.6mm PCBs and they are cheap with the Chinese PCB manufacturers
