The provided binaries are compiled for the Raspberry Pi Pico and have been tested to also run on Adafruit Feather RP2040 boards.
 
 ### Hardware Setup (Raspberry Pi)
 1. Obtain a Raspberry Pi single-board computer (any model). Due to the unavailability of Raspberry Pis, using any other computer with an external LED driver is recommended (see above).

 #### Common Issues
 LEDControl and the Raspberry Pi audio subsystem cannot be use together since they both use the PWM hardware. On some Linux distributions, you must disable the audio kernel module by commenting out the line `dtparam=audio=on` in `/boot/config.txt` or by creating a file `/etc/modprobe.d/snd-blacklist.conf` with the contents `blacklist snd_bcm2835`.
