Selling three Charybdis builds. Transitioning to ZMK wireless builds and reducing extras and offsetting expenses, and I hate to see them collecting dust.
These needs a new home where they will be appreciated and used daily. All are fully functional, well tested, and have been my daily drivers at some point.
Local pickup in Milton, ON, Canada is also available if preferred.
These boards are reliable and should not need repairs under normal use; if you ever want to service or modify them later, I can share full details and provide support. Basic soldering iron and multimeter skills might be required.
