Le oeuf
About the Le oeuf PCB
Le oeuf is an open source PCB design by eggsworks, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 215.1 × 81.2 mm, with 75 components from 5 distinct parts.
Other key parts include the 74HC595D,118. By type, the board carries 37 switches, 36 diodes, 1 IC and 1 connector.
It belongs with the keyboards designs in this gallery.
