Cipher2
About the Cipher2 PCB
Cipher2 is an open source PCB design by k20human, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 42 mm, with 9 components from 8 distinct parts.
Other key parts include the Pro Micro 5V/16MHz. By type, the board carries 4 connectors, 3 resistors, 1 IC and 1 capacitor.

La carte de raccordement du deck : elle porte le Pro Micro sur embases, les quatre connecteurs des commandes, et rien d'autre.

100 × 42 mm, deux couches, 1,6 mm, cuivre 35 µm. Elle se loge dans la bande libre du boîtier, sous le hub USB, et n'est jamais visible.
Elle a d'abord été conçue comme une façade portant le bouton, l'encodeur et le trackball soudés dessus. Le boîtier a tranché autrement : les trois commandes sont montées dans le plastique, loin les unes des autres, et rejoignent la carte par câble.
