Does not function.
I've purchased two of these and they both seem to be dead or non functional. I tested by connecting to pin 11 (gpio17) on a raspberry pi and running a test python script. There is no activity. Has anyone else gotten one to work? Also these were just the module in a box. no anti-static or anything.

BEST TRANSMITTER FOR THE PRICE
works incredibly well up to 400Meters with 3.3V on a custom designed rasberry pi pico W that i made in my garage with temu and scrap parts with 32kb of memory ripped off of a digital alarm clock
Yes, I recommend this product.
