Overview

Control board is now done as well!
There is a lot going on so I’ll break it down a little.

MCU

There is an STM32G431. It functions as the brain of the device. It handles everything: current regulations, communication with the user using the display and USB.

VRM

Board is powered from 24V DC and it is regulated to 15V and 5V with linear regulators. It powers the frontend and op-amps on power boards. There are 2 more rails: 12V for fans and 3V3 for entire digital section. Both are switch mode regulators, since both need to be high current and noise is not a big concern

Now I will wrap up the project and make it ready for funding. It looks great and I’m really proud of it.
