My place to store and improve KiCad boards and schematics

I have a couple MCP4725 boards and I decided I want to copy the layout to KiCad so it's easy to use later in some CV/Gate interface for music production, volume control for an amplifier and so on. Those worked for me in Arduino, giving a stable amount of voltage.

Attention! Output voltage will depend on the input! To imagine how that works, let's say you have a 5V source. Integer you are sending using I²C varies from 0 to 4095 (12-bit). Now, when you have 5V input and 4095 on I²C, you'll have 5V on the output. If you set 0 on I²C, you'll get zero voltage. But you can put any value between 0…
