6 layer MCU: common questions

What microcontroller does the 6 layer MCU use?

The 6 layer MCU is built around the STM32F405RGT6, from the STM32 family.

How big is the 6 layer MCU PCB?

The 6 layer MCU measures 50 × 50 mm, has 6 copper layers and is 1.5782 mm thick.

How many components are on the 6 layer MCU?

71 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the 6 layer MCU design files?

From the BaktiyarBr/Rock_Controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 6 layer MCU design in my own project?

The repository has no license, so all rights stay with BaktiyarBr. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 6 layer MCU without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
