RF M4 Receiver Momentary Type Question

Post by AuroraJim »

I'm looking for a 315MHz receiver like this one, but it needs to be compatible with a HomeLink garage door remote. Does anyone know if the M4 will work with HomeLink? My garage door opener is 315MHz, and it works with HomeLink. I understand the M4 only has 8 "DIP switches" (actually solder points) but my garage door opener has 12. Thanks for any help or info.

The M4 receiver is based on the Princeton Technology PT2272 chip. There are versions of this chip that support as many as 12 address pins.

I don't see anything in the HomeLink literature detailing what they use. Other than experimentation, your best bet is to ask HomeLink if their product is compatible with the PT2272.
