This is an Ergonomic PSeudo SPlit 75-key Keyboard. It was desinged after two years of working with a Truly Ergonomic CLEAVE Keyboard and also inspired by the Redox Keyboard.
This keyboard is designed to work with the layouts of the Neo Family and the ReNeo software.
The firmware was created using QMK. See also the files in the QMK Repo. But I am still using the ReNeo software. And the ReNeo software offers more possible key functions and in total six layers. The file containing the used layout to define those layers can be found here.
A detailed description of my thoughts and some expiriences during the conception and manufacturing of this keyboard can be found here.
