Perfboard
About the Perfboard PCB
Perfboard is an open source PCB design by Windfisch, published on GitHub. It is a 2-layer board measuring 50.8 × 101.6 mm, with 49 components from 10 distinct parts.
Other key parts include the 6N137 and BluePill. By type, the board carries 24 resistors, 8 connectors, 8 diodes, 4 ICs, 4 capacitors and 1 module.
It belongs with the audio designs in this gallery.
From the project
A open source, open hardware up-to-16x USB-MIDI-interface for around 15 bucks in its smallest configuration.
This page describes the hardware itself. A build manual is available here.
Midikraken boards are meant to be stacked using M3 spacers and screws. In such a setup, one "master" exists that holds the microcontroller with the USB port, and zero or multiple "slaves" are daisy-chained with their upstream ("from master") or downstream ("to slave") ports.

Perfboard: common questions
How big is the Perfboard PCB?
The Perfboard measures 50.8 × 101.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Perfboard?
49 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Perfboard design files?
From the Windfisch/midikraken repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Perfboard design in my own project?
The repository has no license, so all rights stay with Windfisch. Use it as a reference, and ask the author before reusing the design.
