Utility modules (jack, power, etc.)

Jacket module

is used to connect up to three Eurorack 3.5 mm patches to the Microrack setup.

Known issues

  • board outline and silkscreen is needed

DC module

for power the breadboard setup. It is possible to power microrack by barrel jack (5 to 12 V) or USB type-C

  • up to 2 A by +5V
  • up to 1 A by +12V
  • up to 150 mA by -12V

Known issues

  • LDO on +5V cannot handle so much power
  • Isolated DC/DC on -12V breaks sometimes
  • MT3608 works unstable and burns out sometimes
  • board outline and silkscreen is needed

Power extender

to power up more than one breadboard or rack. You can use 4-pin cable with common JST 2.5 connectors

Known issues

  • indication LEDs should be on the bottom side of the board
  • board outline and silkscreen update is needed

There are images of the latest released version of the modules. This is not the final product, development is in progress.

if there were a backer add-on with a few jack modules, I’d add them to my kickstarter pledge now, rather than having to wait for them to be orderable later.

Yes, we’ve just added More I/O Jacks Addon. Check them out at the order page.

With the input jack module it might be an idea to use stereo inputs. That way you can get 6 mono inputs using adapters and you will only have to use one jack if you want to run a stereo device into the system. This doubles up the inputs without taking up any additional real estate.

The jacket module is a very simple passive module designed for integration with modular systems and synthesizers that operate with modular signal levels. Typically, in this case, they have mono jack outputs.

To connect line-level signal sources, an input jack module is used, where you can set the gain.

Ah yeah definitely a lot better using the module you mentioned for stereo audio.

Would it still not be useful to use trs to be able to double up the amount of inputs using external stereo to mono splitters (ive attached an image) or would the duplicate output for each input be more useful?
