Description
Selling my 2 Caldera keyboards designed by \Christian Selig\.
\Timestamp\
\- Boards made following Christian guide.
\- Switches: Kailh Choc Low Profile - Red Pro
\- NRF52840 microcontrollers
\- Price: EUR 130 per unit, included shipping in Europe
Notes:
\- The white keyboard has a little crack in one of the screw joints. It doesn't affect behaviour and it is invisible with keycaps.
\- JLC3DP did not do a great job with the plastic bottom plates, they are not very sturdy. It would benefit for reprinting the bottom plates with a 3D printer (STL files here https://github.com/christianselig/caldera-keyboard). I mean it works, it is a bottom of a keyboard that nobody sees but still.
\- Extra EUR 20 to upgrade NRF52840 to nice!nanos.
\- Extra EUR 15 to include keycaps
