About the Nullwing PCB

Nullwing is an open source PCB design by CityRunner, published on GitHub. It is a 2-layer board measuring 212.2 × 69 mm, with 85 components from 7 distinct parts.

Other key parts include the Nice_Nano_V2. By type, the board carries 43 switches, 40 diodes, 1 IC and 1 battery holder.

It belongs with the keyboards, iot & wireless and power & battery designs in this gallery.

From the project

Through hole mechanical keyboard with rotary encoder

Nullwing is a DIY keyboard project designed for easy assembly and hand soldering.

This PCB utilizes Choc Mini switches for a low-profile design. It is mounted using standoffs in a specially designed case for stability and secure placement. However, the case itself is not fully implemented, so users will need to create their own enclosure.

The firmware is incomplete too and unlikely to be finished, requiring users to develop or customize it themselves.
