This is a PCB version of the HAGIWO Display Eurorack module. The design was published on Github by mzuelch and we put together the design & kits in our lab.

The module is a Arduino-based simple OLED Display that has a 4 modes as of now. (See the repository for updates / new features in the future) The microcontroller can be reprogrammed easily with the Arduino IDE and a USB cable.

Features:

• Panel Design by bkrsmdesign
• 128*64 pixel 0.96inch OLED display
• Rotary encoder with PUSH Button
• GAIN attenuator
• AC/DC switching toggle switch
• TRIG IN
• INPUT (normalized)
• OUTPUT

• Voltage 0-5V

• LFO / EG mode

• 1 shot mode
• spectrum analyzer mode
• whatever you will come up with

SCOPE comes in three flavors: basic kit, full kit and built unit.

The full kit includes everything needed to build one module. Also it has all the passives presoldered, so you just need to solder the power socket, 3x thonkiconns jacks, 1 attenuator pot, Encoder, Display, microcontroller, miniature switch and that´s it. it´s ready. The microcontroller is included and programmed.

The basic kit includes everything except:

1x Power connector 1x ~10cm Cable 1x Microcontroller (Arduino nano v3) 2x 15-Pin Female header 1x SPI OLED Display 1x Rotary Encoder & Knob 1x attenuator pot 3x thonkiconns 3,5mm Jack 1x on-off-on 3 pos miniature spdt switche

Basic Kits also always have the smd parts presoldered.

DIY Info:

Building the Module is simple and suited for beginners as there are only a few common parts needed.
