CC1101 Wireless Module with SMA Antenna Wireless Transceiver Module 315/433/868/915MHZ

Works with hunter fans on 303mhz frequency. Use rc_switch tho bit good range and power. Good value as well

I’ve bought a few of these and I think this is the best one. Build quality is very nice, it just feels better quality than comparable versions, very good range and connectivity.

Fantastic! Worked perfectly on my first try. Got it up and running as a 433.92mhz controller for my old RF blinds and was able to modernize them using ESP-IDF Matter. Saved me from having to buy new blinds motors with modern comms protocols.

4 stars because it arrived with a bent pin. No protective foam piece over the pins like components usually ship with. Using this with an ESP32 on 303mhz for RF fan control, and it works great with TX and RX. The arduino firmware is tricky, you must initialize it differently on different boards, keep that in mind. Otherwise it works as it should and avoids the need for separate modules for TX and RX. Good deal.

Good power, straightforward wiring, a little temperature sensitive

Everything went ok.

The antennae it comes with is ideal for 433mhz. Maybe it'll pick up 315 anyways as detailed on the product page and the title? Nope. All I could get out of it were hints, clues, and statements that it could not pick up the frequency, despite an SDR having no problem on the same frequency. Have no use for the other frequencies and no other devices to test the other frequencies with. It might be a 5* product in the other frequencies, but not 315.

Same as some others here. I tuned this bad boy to 303Mhz to control a fancy ceiling fan with light. Used ESPhome as firmware; Responsive, good enough range.
