LinxRF - A simple data radio transceiver design based on the Linx Technologies LC-series radio modules

• Design uses Linx Technologies LC-series radio modules
  • Transmitter: TXM-XXX-LC (replace XXX with frequency 315,418,or 433MHz)
  • Receiver: RXM-XXX-LC-S (replace XXX with frequency 315,418,or 433MHz)
• Operating range approx 50-150ft (varies with environment and data rate)
• Max Data Rate: 5000bps (can support RS-232 at 4800baud)
• Design can operate from 3V-5V
• Low power: (approx) 2mA receive, 10mA transmit
• Transmit and receive antennas can be simple 1/4-wave whips (vertical wire, 1/4-wavelength long)
• Inexpensive: one complete transceiver can be built for ~$20
• Small: without interface connectors, transceiver fits in less than 1.5"x0.5"x0.25"
• Transceiver Schematic
• For AVR users, the AVRlib "stxetx" function library will allow you to send data packets over this and other radio links with strong rejection of communication noise. The "stxetx" protocol provides packetization and checksum protection for user data. The "stxetx" function library is available now, with example application code coming soon.
