Daisy seed power and opamps

Handy Breakout PCB for the Electrosmith Daisy Seed that can be very helpful for prototyping, especially when working with eurorack signals.

- DC DC converter from +/- 12 Volts eurorack power to +5 Volts for the daisy seed.
- Opamps for audio in and audio out, eurorack level.

When using long headers it can be plugged into a breadboard for fast prototyping while using the clean power and the op amps.  

Bit fiddly to install on breadboard, but once in place worth the hassle.

To install on breadboard i use long female headers.  

-> Daisy seed with normal male headers plugs in the female headers 

-> female headers through PCB plug into breadboard.

All daisy pins are then available on the breadboard, audio in and out through opamps are available as well as +/- 12 Volts.

I have put up a small website with more pictures, links and code.

Also there you can find an Eight channel input protection and multiplexer board that scales Eurorack level -/+ 5 Volts to safe 0 – 3.3 Volts, these scaled signals can be used directly or via the multiplexer thats on board.

These 2 breakout boards helped me tremendously while developing DSP audio on the Daisy Seed and interfacing with eurorack. 

The daisy seed breakout boards are an open source project.
