Wireless 4 Channel RF 315MHz Remote Control and PT2272 Receiver Module [Momentary]

  • RM15.90

  • Ex Tax: RM15.00
  • Product Code: Wireless Controller PT2272
  • Availability: In Stock

Available Options

Add a simple wireless control to a device, no addressing, no programming – used a 315MHz remote with this receiver and you have wireless control up to 100 meters away under ideal conditions!

The M4 momentary type acts like a push button – when the A button is held down, the matching pin goes high. When the A button is released, the matching pin goes low. The pins only go high when a button is pressed.

Address Setting

We generally use the 8-bit address code and 4-bit data code. Pin 1~8 of encoding PT2262 and decoding PT2272 circuit is address pin. There are three states: vacant, high, low. So it has 6561 valid address. Only while the transmitter PT2262 and receiver PT2272 have the same address, they can communicate. So before we use them, we have to set their adresses the same.

As shown above, jumper pad area is composed of three rows. The middle 8 pads are pin 1~8 of PT2272 decoder chip. from the left where marked 1, they are pin 1 to pin8. On the right of the top row there marked an "L", where means this row is connected to GND. And the "H" means they are connceted with positive power supply. If you solder the address pin with the "L", it means you set the pin to low. If you solder it with "H", it means high. And if you leave it alone, it means vacant.
