I want to get 3 XBP24C radio modules and mount them on the XBee Interface Boards that came with the development kit XBee-PRO 900HP Development Kit. If I do this will the modules communicate? Please advise.
You didn’t mention if XBP24C module is Through Hole or SMT.
Digi provides just 2 types of interface boards; one for all types of SMT modules and other for all types of TH modules.
Thus, if you have TH XBP24C modules, then they will work well with interface board that came with XBee 900HP modules.
