GUI-O FM PLL Radio reciever

[gammda]

I found this simple FM radio module.
https://www.amazon.ae/Digital-FM-Radio-Module-76-0MHz-108-0MHz/dp/B01N4AHISZ

It offers control via UART.
Added Arduino NANO, Bluetooth module HC-06 and of course using GUI-O.
The result is here.

Here is also Youtube video and schematic.
