Being tired of perfboard full of wires I designed this modular board for easy and quick prototyping projects. The goal is to put together eurorack module using digital processor (STM32F030K6). It has a 2*12bit dac (MCP4822) (that can be changed for the MCP4802 as well), 6 (CV-able) inputs to the ADC and three outputs that can be connected to the PWM outputs or the DAC outputs. It also offers 4 logics output to the eurorack standard (10v).

The important fact was to create something that could be used for several projects and not having the remaining boards left unsued.
