433MHz Wireless Modules MX-FS-03V & MX-05

Low cost superheterodyne receiver and ASK transmitter. The transmitter consists of a single digital input pin that, when pulled high, will cause the transmitter to continuously transmit a signal at 433MHz. Conversely the receiver has a single digital output pin that is high when a signal is received. The simplicity of these modules makes them ideal for applications where low power and low data rate (4Kbps) applications are required. The modules operates on a single channel so multiple transmitters can transmit to a single receiver and vice versa.



For Arduino users we have created an exclusive library (HCWireless) that makes transferring data over these modules as simple as possible. 

Please note to achieve maximum transmission range an antenna must be fitted. See forum link below. The receiver has an auto gain circuit and when not receiving a signal will set its gain to maximum. When this occurs the output pin on the receiver may randomly toggle as it picks up random signals or noise.

More information about these modules including library and example sketches can be found on our support forum here.
