With the success of the Mosfet running well, I must now move on to the TX/RX thingy. I've downloaded all datasheets from Rev-Ed and Digi-Xbee. I think I've gotten the gist of it, Picaxe at 5V, Xbee at 3V etc. with dividers and so on... I've bought 3 modules (1mW) from Rev-Ed, one as "master", one as possible "repeater" half way, one at PC/Picaxe side. I need to cover about 100 to 150m distance. I have the wire antenna modules. I will connect to a 40x1 "master" and a 28x1 "slave"/PC side.
Do I need to connect the Xbee reference voltage ?
What MUST I ABSOLUTELY look out for to prevent damage ?
How do I determine what and "how to" use as Ground Plane ? The Xbee will sit on the raised 2mm pitch Rev-Ed SIP header pins.
Do I need to "install/insert" something to assist the antenna with "ground plane" for max distance ? Any push in a direction to search or get to a site where this is explained will help.
Thanks in advance
