FM module - idea

3rd-party modules

I think it might be useful to use Bluetooth connectivity (and a “companion app”) to allow the user to stream audio on FM frequencies (87.5 to 108.0 MHz). i know that in many states it is illegal to broadcast without a license, but it should be considered as an idea for an external module to be attached to the gpio.

I hope that this idea can be taken into consideration at least by the diy community, I am attaching the photo of an fm module for arduino:

forgive me for my english (google transalated), thanks for reading and stay safe out here!

There is a lot of FM bluetooth transmitters for cars. Do we really need one more?

honestly yes, it would be a very portable solution, charged at 5v (not the 12 of the car) and usable even on old stereos if your phone does not have a 3.5 jack.In any case, I think it could also be useful to experiment on a platform where competent people are / will be present. It must also be considered that it is a very little treated topic from tutorials and paper guides

Can’t the CC1101 in this already transmit FM this this range? Is it just the antenna that won’t do these frequency ranges?

Nope, it can’t do the FM range. Moreover, it can’t do analogue radio.
