Mechanical drawings of XIAO

Hello,



I find the Seeeduino XIAO really interesting. However I would like to design a board to solder it and purchase the XIAO and the board at the same time to save shipping cost.



I miss the mechanical drawing : distance between the pins rows, exact position of pads (VIN, GND, SWDIO, SWCLK) so that I would be able to design a footprint



Could you provide these informations ?



Best regards

Hi,



You could use the XIAO Eagle SCH file, Seeeduino-XIAO-v1.0.zip.

A related question - do the mounting pins for the USB-C connector protrude through the bottom of the PCB.



I was looking to mount the XIAO directly to a PCB using the castellated connections without header pins, but this assumes the USB-C connector does not interfere. Or do I need to place clearance holes in the relevant positions?
