Interphase is an open source PCB design by Durburz, published on GitHub under the MIT license. It is a 2-layer board measuring 142.2 × 132.1 mm, with 115 components from 13 distinct parts.

Other key parts include the Core51822B and MCP1640. By type, the board carries 66 diodes, 33 switches, 4 ICs, 4 capacitors, 4 resistors and 2 inductors.

It belongs with the keyboards designs in this gallery.

From the project

a mitosis clone with more keys!!1eleven

interphase is a open-source mechanical keyboard. Kudos to reversebias, as I got inspired by his fascinating mitosis keyboard (https://github.com/reversebias/mitosis-hardware). The only problem was the lack of keys for a full german layout + number row.

Therefor, interphase is a kind of ISO-compatible layout with some minor modifications.

Update on battery life: The AAA batteries (Duracell) per keyboard-half are still going strong. After 5 months of heavy usage at work, they only dropped to ~1.4V. Therefor the total lifetime of the batteries will be approximateley 1 - 1.5 years, as the…
