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

DIY Info:

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