Are the SPSGRFC-868 and SPSGRFC-915 Spirit1 radio modules physically different? Since the antenna for these modules is separate, is there a need for physically different modules?

    Welcome, @PVilb.1​, to the community!

    the SPSGRFC-868 and SPSGRFC-915 are identical in terms of board and dimensions, only the balun and carrier frequencies are different. Of course, the antenna used must match the module used, i.e. 433/868/915MHz.

    Does it answer your questions?

    Thank you Peter. We were hoping that the modules wouldn't be physically different from PCA inventory management, but since the balun is different we will have to forecast, build and inventory separate North American and European PCAs.
