Questions about SD21 and xBee modules
August 31, 2010
My parts arrived today, but I cannot find any useful information how to connect them.
So, once again I am asking LMR to help me :)
The questions are:
1. How do I connect SD21 to my Picaxe28x1 chip? I guess using these, not sure though, that's why I am asking.
2. Do I need a second power supply for the SD21?
3. Do I still have to change the baud rates, invert signals, drop the voltage to 3v, or do anything similar for the xBee modules, if I am using Adafruit Adapter ? (The Picaxe side)
4. For the pc side I will be using xBee Explorer USB from SparkFun. Do any of the above apply as well?
Thank you :)
