2X CC1101 Wireless RF Transceiver 315/433/868/915MHZ + SMA Antenna Wireless Module

Got these for a flipper extension board and they work great. Good seller.

Did not come with pins and the solder job where the pin holes was bad and not cleaned up. Looked like someone desoldered it with their eyes closed

Not only were these not as pictured - 8 pin modules delivered rather than 10 pin. They also don’t have a pinout provided or printed on the circuit board.I managed to get one to work with the help of a pinout from another version, but the other module doesn’t seem to function at all.I’m not super impressed. 2 stars for now unless I get them both working, then I’ll upgrade the review to 3 stars.

These modules worked fine in my application, easily achieving 500+ foot range in the 433 MHz band.I did benchmark their performance a bit, and they perform acceptably on the 315 and 915 MHz bands as well, though they're best on 433 due to the included antenna and coupling network being optimized for that band.I can't tell from cursory examination whether the IC is a real TI CC1101 or a clone, but if it's a clone it's a good one. I haven't observed any compatibility or performance problems.

CC1101 works you may want to buy better SMA antennas for it how ever.

Used these to increase the range on the Flipper zero. No complaints whatsoever.

Listing is misleading. This chip is for 433MHz ONLY, not the multiple frequencies advertised. Unfortunately for me, I intended to use the upper range of just under 1GHz so it's basically useless to me.

Will update review when i test my project
