How to select electronic components

[mobilemajia]

Dears,

Good day! The motioner project is a great well designed project :) I am an electronic fan and I learnt this project is a happy journey!

I found a problem when I tried to start building the project. It seems that some electronic components obsolete when I want to buy them. One of them is "XBee Wi-Fi" in the buying list in the following links:

XB24-WFPIT-001:

It is not available now. Do you know where to buy it? Or is there another choice?

I find an alternative component is alike it. I don't know whether it is good for motioner or not. If it is ok, do I need to change the code in order to adapt to the new electronic component? Thank you so much.

The main differences between these two components are the "data rate" and "interface type".
