Puffer
About the Puffer PCB
Puffer is an open source PCB design by DuBento, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 116.1 × 92.5 mm, with 42 components from 9 distinct parts.
Other key parts include the nice_nano. By type, the board carries 18 switches, 18 diodes, 1 IC, 1 connector and 1 battery holder.
It belongs with the keyboards designs in this gallery.
From the project
Split Ergo Mechanical Keyboard
Wireless Ergo Split Mechanical Keyboard. Based on the temper keyboard, the Puffer has been upgraded for more comfortable use by those with larger hands.
- Increase spacing between keys, from choc spacing (18x17mm) to 19x18mm - Optional direct soldering of switches or hotswap pads - Added tenting puck support - Support for SMD Diodes only
- 36-key split keyboard 3 rows x 5 columns + 3 thumb keys per half - Wireless - Reversible PCB - Custom spacing 19x18mm - Nice!Nano (and similar) compatible
