CK980C by Upas (Group Buy) - MX and Naevy EC

"A modern tribute to electro-capacitive excellence."

The Story

Designed in-house by Upas and brought to life with community collaboration, the CK980C is a spiritual successor to the beloved FC980C layout—modernized with both EC-first and MX-compatible variants, a built-in USB 3.0 hub, and a thoughtful mounting system that bridges old-school feels with modern engineering.

Launching as a global group buy, the CK980C invites both EC veterans and curious newcomers to experience a legendary form factor with renewed flexibility and a dialed-in building experience.

We’re proud to partner with Upas and the Cannonkeys Team to bring this to market as part of our expansion project for Topre availability in the UK and Europe.

This listing is for the version of the keyboard which accepts Naevies (MX / Dome hybrids), and traditional MX switches.
