These modules are sourced from China and can be bougth via ebay.

They can be used as a cheap replacement for RFM12 to switch radio outlets.

Technical Specifications

  • Receiver module parameters
    • Product Model: MX-05V
    • Operating voltage: DC5V
    • Quiescent Current: 4mA
    • Receiving frequency: 433.92MHZ
    • Receiver sensitivity: -105DB
    • Size: 30 * 14 * 7mm
    • External antenna: 32CM single core wire, wound into a spiral
  • Transmitter module parameters
    • Product Model: MX-FS-03V
    • Launch distance: 20-200 meters (different voltage, different results)
    • Operating voltage: 3.5-12V
    • Dimensions: 19 * 19mm
    • Operating mode: AM
    • Transfer rate: 4KB/s
    • Transmitting power: 10mW
    • Transmitting frequency: 433M
    • An external antenna: 25cm ordinary multi-core or single-core line

Remark

  • VCC voltage module operating voltage and good power filtering;
  • Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor, the length of the antenna 433M of about 17cm;
  • Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.

Connection

The DATA pin of the transmitter module is named GENERIC_ASK_TX in Ethersex's pinning. The example below uses PA0.
