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

Everything went ok.

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.

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

These lil babies here are so valuable they worked well no issues with the quality or design of the CC1101 transceiver

I purchased this CC1101 module expecting basic RF functionality. It powers on and SPI communication works well enough to get a connection (CC1101 connection OK), but that’s where the good news ends. The GDO2 pin never reaches a solid 3.3V during transmit — usually maxing out around 2.7–2.9V — and no RF signal is detected, even with confirmed RF codes and wiring. Flipper Zero shows nothing during transmissions, and the fan never responds. Build quality is rough, with dirty pins and uneven soldering. I tested multiple boards from the pack with the same issue. If you’re serious about RF, skip this and buy a quality CC1101 from a reputable seller. Returning this one.

Ok
