Pragmatic
A split keyboard family by u/james_sa with a central controller piece: Pragmatic.
Published September 6, 2022
Would you like to contribute to this year's MK Advent Calendar? Here are the guidelines for authors, along with last year's edition for reference.
James Sa (aka jamessa or james_sa) published his Pragmatic open-source keyboard family, with three models at the moment.
Pragmatic 72 is a 6x6 ortho (per half) with F-row, Pragmatic 60 is similarly ortholinear but without the function keys, finally, there's a 34-key split ergo version with columnar staggering and two-key thumb clusters.
These models share both the logical layout (sort of) and a controller board outsourced to a separate third PCB, connected by ribbon cables and IDC connectors.
The basic idea for “Pragmatic” is using a single micro controller for keyboard matrix scanning. It’s my keep it simple solution during this MCU shortage period – james_sa.
