Hy
I have changer the a388 som of my clearfog pro for a cn9130.
One question please ^^ : is there a heatsink for the cn9130 som?
The one i have for the a388 doesn’t match 
Thanks by advance
It is the same heatsink. I have both a388 and CN913x heatsinks and both are identical. If you are seeing gaps you may just need thicker thermal pads.
