+This firmware offers currently these variants (selectable in [platformio.ini](/platformio.ini) or [config.h](/Inc/config.h)):
 - **VARIANT_DEBUG**: In this variant the user can interact with sideboard via a Serial Monitor to observe and check the capabilities of the sideboard.
 - **VARIANT_HOVERBOARD**: In this variant the sideboard is communicating with the mainboard of a hoverboard using the [FOC firmware repository](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC). This Variant is not yet fully tested!

 ## 3D Visualization Demo
 
-By [converting Quaternions to Euler angles](https://en.wikipedia.org/wiki/Conversion_between_quaternions_and_Euler_angles), we can make a [3D visualization example](/docs/sketch_processing/sketch_processing.pde) in [Processing](https://processing.org/) as shown below. For this Demo use the VARIANT_HOVERBOARD.
