Send or receive digital data, control or command information with LR Series transmitter and receiver modules. Use the receiver with a matching or compatible Linx transmitter for reliable one-way wireless communication at 315MHz, 418MHz or 433MHz. Compared to 2.4GHz modules, narrowband modules from Linx provide longer range and lower current consumption at a more cost-effective price.


  • Attain longer range: send or receive digital data from up to 3,000 feet (914 meters) away when used with another LR Series or LT Series module
  • Integrate with ease: simple hardware configuration lets you transfer raw data without protocol constraints or the need for user programming
  • Save power: low current consumption compared to competing modules extends battery life
  • Simplify design: modules and antennas are the only RF components you need; no tuning required
  • Streamline production: save time and money with modules that are already tested
