Radio Communications Board
This radio module removes all of the overhead normally associated with radio communications.
All of the necessary construction of packets, encoding/decoding and timing is carried out at the module.
To use these modules, simply connect them to a com port and using either your own software or Hyper terminal set to 19,200 baud, 8 data bits, 1 stop bit, no parity and no handshaking, then, whatever you type in one end will appear exactly the same at the other.
