Bus enable
About the Bus enable PCB
Bus enable is an open source PCB design by carr-james, published on GitHub. It is a 2-layer board, with 4 components from 2 distinct parts.
Other key parts include the 4066. By type, the board carries 2 ICs and 2 capacitors.
It belongs with the audio designs in this gallery.
From the project
Reusable Eurorack circuit blocks (KiCad 10 design blocks) and house design rules
Connects up to four signals to shared buses, and disconnects them all when the module is not the active one.
Four analogue switches, one common control. When EN is high all four channels pass. When EN is low all four are open and the module is invisible to the buses.
This is what makes a chained module safe. step-counter gives an EN signal ready made: its HELD output is high on exactly one module in a chain.

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