The CB280CS has exactly the same features as a regular CB280 chip except it's in a chipset format. By using the CB280CS, the user is able to solder the chipset directly on to their PCB. This will lower your overall production cost while integrating CB280 into your product seamlessly.

Since this chipset has same features as a regular CB280, we recommend you develop your applications on the CB280 before going into production with the chipset version.
