I'm looking at Figure 64 of BBxM manual: it don't specify the distance
between left border and holes of the slot (similar to B/C),
so I'm not sure where to place that with regard to LCD slot on my
board. could some one tell me that distance please?
You can download the Allegro viewer and open the PCB files. The viewer has a measurement tool that can be used.
Similar way is in the CAM350 when you open gerber files
thanks guys, the offset seem to be 4.83/1.4mm between J11 and main
header. going to verify soon
