All ok. Other comments: - Please place resistor R62 on the bottom side of the PCB. I'm not sure that it would fit stacked under the power supply module, and since there is space on the bottom layer, better not take this risk. - There are component clearance violations in the top right area (C178, U17, F1...) and between C1 and the test points, but I guess you already spotted them. - There is a problem with the top hole of J2. - There are several vias between power plane cut-outs, for example at the right of R50. Is that OK? - Altium says that some 3V3 power signals are not connected, even though they are connected through the plane (see attached screenshot). For example, on C127. But that's perhaps because I did not rebuild the polygons correctly, did you do anything special? - You can include a "M" logo as well (attached file). > Only connectors I'll decide the final footprint these 2 days and > generate gerber files.
