description: |
GPIO pins exposed on the Glove80 internal extension header.

See https://docs.moergo.com/glove80-user-guide/appendix-more-customizations/

Both sides of the Glove80 split keyboard expose a set of 6 extra GPIO pins
for customization, with different underlying nRF52 pins used on each side.
This nexus node allows referencing the pins generically without being tied
to a specific left/right side pin assignment.
