Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: None. We are no longer selling these modems, but have a look at our other wireless solutions. This page is for reference only.

Description: 433MHz Long Range Radio from HAC. These small modems use a seamless serial interface - whatever serial character enters the TX pin at 1200bps shows up on the other unit's RX pin. All buffering and error detection is handled internally. And the best part - with 10mW output, it reaches over 1000m!

This unit can be attached to TTL level serial (for microcontrollers) or directly to RS232 for incredibly simple serial cable replacement!

Specifications:

  • Operating Voltage: 3.3V-5.5V
  • 1200bps over 1000m
  • Modulation type: GFSK
  • 8 Channels jumper selectable
  • Low power : 30mA RX, 40mA TX, 20uA Sleep
  • Small footprint size: 26x47mm

Supported Antennae: Kit comes with 1/4 wave 50Ohm antenna and communications cable!

Sold in single units.

  • Anyone know where to get a similar 9 pin cable? I want to use one to prototype with and another to wire into place in the final enclosure.
    I haven’t seen one similar in SFE’s inventory here.
    Thanks

  • can this antenna work with the 1-20 frid and arduino?for the arduino,uno or romeo type can be used with this antenna?

  • I have two arduinos
    if i buy two of these
    can i connect two cable to each arduino (tx/rx)
    and then if i serial print something on the one arduino that message goes to the second one
    and the reverse?
    thanks

  • Are these transmitters full-duplex? Can they send & receive at the same time?
