Den v3: common questions

What microcontroller does the Den v3 use?

The Den v3 is built around the STM32F446RETX, from the STM32 family.

How big is the Den v3 PCB?

The Den v3 measures 98 × 98 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Den v3?

57 components, from 34 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Den v3 design files?

From the makizusi/-circuit repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Den v3 design in my own project?

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

Can I test firmware for the Den v3 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.
