It is functional on StickC Plus 1.1, StickC Plus 2 and Cardputer. On the Cardputer, it is not possible to access the SD Card using the RST pin. Needs future adjustment.
Change made without removing StickC Plus 1.1 from the LITE list.
When used with the Cardputer and the SD Card Sniffer, the RST pin (CLK on the SD Card Sniffer) makes it impossible to use the SD card. We are checking other possibilities for future use.

Proposed Changes
Some changes were made to the pins and menu so that FM Radio would work on StickC 1.1 and on Cardputer with SD Card Sniffer.
Verification
2 Situations:
1 - The pins on the Wiki are inverted, I will change them.
2 - It broadcasts via FM Radio the audio that comes from the P2/P3 connector, it still does not reproduce the audio in MP3/WAV from the StickC/Cardputer, therefore, it needs an extra device (a cell phone or computer) sending the audio via P2 cable to the board.
Testing
It was tested with the Cardputer and the StickC 1.1 and I was successful, with a small wire as an antenna I was able to reach a few meters of distance with sound quality. Funnily enough, I have a MAONO audio card and in addition to the music playing, I was also able to add some effects and use the computer's microphone. It was very similar to a radio station :)
On the cardputer with the SD Card Sniffer, use the CLK pin connected to the RST of the FM transmission card.
Further Comments
In several countries, FM broadcasting is prohibited, check this information and carry it out in a controlled environment.
