Post 4 Chan 433MHz wireless receiver with remote fob (HCWILS0003)
Image



This item is a wireless 4 channel remote controlled module with a battery operated transmitter fob. The fob has 4 individual buttons which, when pressed, will trigger one of the 4 digital output pins on the receiver module. When no buttons are pressed all 4 digital pins will remain low (0V). When one of the transmitter buttons is pressed the appropriate output pin on the receiver will go high (5V) and will remain high until the button is released.

These units are based on the PT2262 & PT2272 433MHz transmitter and receiver IC which means they are compatible with our 433MHz PT2262 wireless transmitter/receiver module. See items HCMODU0048 & HCMODU0049.

The transmitter module includes a 12V 23AE alkaline battery and the receiver module can be powered by a single 5V DC supply.


Notes:

To obtain maximum receiver range an external antenna should be attached to the ANT pad on the receiver module. We recommend a length of single core wire measuring 23.8cm (1/4 wavelength) in length.

This is a short range device operating in the 433MHz spectrum. As with all wireless transmitters please make sure this device is legal to operate within your country.

nice looking module
couple of questions:
a) is the 7-pin header already connected?
would be handy if it wasn't!
b) how do you set the "address"?

thanks

Yes the module is supplied with the connector already soldered.

Both the fob and the module come with are supplied already configured to the same (randomly selected by the manufacturer) address so there is no need to program them. However if you wanted to change the address there is a set of pads on the back of the module and and similar set on the PCB inside the fob. You set the address applying solder bridge(s) to them.
