I am currently working on a fun project that needs some wireless communication between multiple Arduinos. I am aware of Xbee and the pre made PCB modules. I am looking for a breakout board of an FCC pre-approved RF module. I know Xbee is that sort of thing but I am planning making a final board and I want to be able to have a few made, and therefore I don't want to have to buy a PCB Xbee Module for each board. My questions are:
Can I just purchase the SMD IC that is on an Xbee module for my device? (I am pretty sure I can)
If the first question is a yes, which type of communication would be best for my needs? Range needs to be at least 20 feet and I really don't need more than 100 and would be okay with 50 to 100 feet max.
If not, does anyone know of a cheap IC that would fit my needs?
Thanks all, I am new to wireless communication so I apologize if this is a really obvious question. All i could find on Google was Xbee or extremely basic RF transceivers that are definitely not FCC pre-approved.
