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

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.

worked pretty well, I used it for my flipper zero, and worked perfect

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.

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.

okay
