I'm really new to electronics and thought I'd build a simple walkie-talkie as a hobby and education project. A friend suggested I consider using the TWS-BS-6 and RWS-374-3 for the radio transmission and reception. But when I looked at the specification sheets here:
There doesn't appear to be analog input or output pins on these boards. I see digital input/output pins though. If I were to use them, do I need to consider the use of analog to digital converters and digital to analog converters as well? I want to make sure I'm not reading these data sheets incorrectly.
