Hello.
I have purchased 2 used Series 1 Pro Xbees to try out basic wireless data send/receive (temp/humidity sensor logging, maybe camera images), but I have never used Xbees. The Xbee Adapter Kit v1.1 (Product ID # 126) looks cost-effective, but why does it have 10 pins when an Xbee has 20 pins? By purchasing this adapter am I losing some I/0 capability? I've quickly searched this Xbee forum and didn't see mention of pin count difference that I bring up.
I don't know my use cases yet, but I didn't want to buy an adapter that short-changed my future connectivity options (PC, Raspberry Pi, or Arduino connections likely). I have an FDTI Friend TTL-to-USB cable, so this should work well with the v1.1 Adapter kit for at least pushing new Xbee firmware.
What advantage does the Parallax USB Xbee Adapter (twice the price, Product ID # 247) offer over the Xbee Adapter Kit v1.1? Direct PC USB connectivity, or full 20 pin Xbee I/O connections? Would a recommended generic starter config be that I purchase one of each adapter, or both of the same type, for my 2 Xbees?
Thanks in advance for any comments on Product # 126 vs. # 247 selection and their intended use cases while I continue to study Xbee forum posts and tutorials.
