* Hardware UART

* Overclocking and underclocking from the menus
|

* I2S audio output
|

* printf (i.e. debug) output over USB serial

The RP2040 PIO state machines (SMs) are used to generate jitter-free:
|

* Servos
|

* Tones
|

* I2S Output
|

# Todo
|

Some major features I want to add are:
|
||||
* Installable filesystem support (SD, LittleFS, etc.)
|
||||
* Updated debug infrastructure
|
||||
* I2S port from pico-extras
