Lichtobjekt: common questions

What microcontroller does the Lichtobjekt use?

The Lichtobjekt is built around the STM32F10XCXT6, from the STM32 family.

How big is the Lichtobjekt PCB?

The Lichtobjekt measures 99.8 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lichtobjekt?

125 components, from 60 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lichtobjekt design files?

From the martinclausen2/Lichtobjekt repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lichtobjekt design in my own project?

Yes, under the terms of its GPL-3.0 license, which martinclausen2 chose for the repository.

Can I test firmware for the Lichtobjekt 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.
