Note: 
1. This board comes with Ender-5 plus firmware, if you use it for Sovol SV01, or Sovol SV03, you will need to flash the related firmware after installing the silent mainboard, please check this page to download the firmware. Make sure that you didn't do other modification which requires compiling the firmware source code. We don't offer tech support for compiling firmware. 

2. Because the supplier of one small part on the mainboard was changed, in order to recognize, Creality marked that batch as Creality V2.2 by mistake. But if the two sides both are black in color, it is the silent board. If one side is green, that's the normal board. 
Sovol SV01 doesn't come with a silent board, SV01+Silent board doesn't mean the silent board is preinstalled. The silent board is shipped separately.
