Welcome to the MOD1 Workshop repository – a collection of Firmwares for Hagiwo's MOD1 hardware module, alternative frontpanel designs and new different firmware versions contributed by fellow enthusiasts. These were made for a Workshop series by modulove in Hamburg in 2024-2025.
Firmware is available in our web-uploader here: Upload MOD1 firmware in Browser
MOD1 Hagiwo is a series of open-source, Arduino Nano-based general-purpose CV/Gate designs for DIY Eurorack modular. These modules are built with a focus on accessibility and customization. examples include:
- Square VCO: A square wave oscillator with V/oct (voltage per octave) support.
- LFO: A low-frequency oscillator ideal for generating vibrato and other modulation.
-
Open-Source & DIY Focused
All schematics and code are freely available, encouraging modifications and custom builds. -
Arduino Nano Based
Utilizes the compact and cost-effective Arduino Nano microcontroller, making it highly accessible. -
CV/Gate Functionality
Designed to generate essential control voltage (CV) and gate signals used in modular synthesis. -
Multiple Firmware Versions
Includes 12 distinct firmware versions developed by Hagiwo, with additional contributions from the community.
