Setting master side

[arielarmijo]

I want to set the master side defining the SPLIT_HAND_PIN as the documentation says.

Is this possible? and which pin of the microcontroller can be used to determine the master side?

best regards!

WHen designing the keyboard, I did not consider any pin to define the split hand. You can change the master side by firmware, including or removing the #define MASTER_RIGHT, or you might use one of the blackpill free pins, depending on what you want to achieve.
