+Adjust the frequency of the main I2C bus via which the right keyboard half communicates with the left half and the add-on modules.
+Example values:
+    * 400000 Hz - Highest speed. This will probably make communication unreliable. Not recommended.
+    * 100000 Hz - Default speed. Should work in most cases.
+    * 10000 Hz - Low speed. Should help when connection is spotty. It'll make initial LED display updates visibly slower.
