SKU: WRLS-006 Category: Tags: , , ,


Looking for a low cost one way data link? This pair can send data at rates of up to 4KB/s in one direction. The receiver operates 5VDC while the transmitter can operate on 3.5 – 12VDC. As the voltage is increased on the transmitter the range is increased – at 12VDC in ideal situations up to 100 meters range can be seen with an external wire antenna!

When the input pin on the transmitter is “High” the output pin on the receiver will also be “High” provided they are in range of one another. We recommend using these with filter capacitors on supplied power.



  • Up to 100M Range
  • Transmitter Voltage: 3.5 - 12VDC
  • Transmission of up to 4KB/s
  • Frequency: 433MHz

    Thanks. But I had been there done that. Programming was not the problem. PIN LABELS on Tx are off they are not as pictured

    I bought it last month. It is working between an ATTiny85, transmitter 5V and a receiver, Arduino Uno, tested LOS 4m successfully.
