Densor: common questions

What microcontroller does the Densor use?

The Densor is built around the STM32L011F3Ux, from the STM32 family.

How big is the Densor PCB?

The Densor measures 46.4 × 18.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Densor?

24 components, from 17 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 Densor design files?

From the TUDSSL/densor 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 Densor design in my own project?

Yes, under the terms of its MIT license, which TUDSSL chose for the repository.

Can I test firmware for the Densor 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.
