Compatibility between the WirelessUSB™-NL Radio Modules Provided with CY3668 Rev. ** and CY3668 Rev. *A - KBA86365

Version: **

 

Question: Is the WirelessUSB™-NL radio module provided with the WUSB-NL development kit (CY3668) Rev. ** compatible with Rev. *A?

 

Answer:

No, the WirelessUSB-NL radio module provided with the CY3668 Rev. ** kit is not compatible with the equivalent radio module provided with CY3668 Rev. *A. Do not use these two radio modules together for wireless application development. You can use only the modules provided with same version of the kit.

However, you can make the two radio modules compatible by replacing the passives C7 and C8 on the radio module provided with the Rev. ** kit. For more information on how to do this modification, see KBA83288.

Note: You can identify the CY3668 kit revision by the sticker attached behind the kit box. Similarly, you can identify the radio module provided with the CY3668 Rev *A kit by the sticker attached behind the module.
