The spacelock firmware can be configured for several use cases.

For each use case there is a config file in firmware/build_config.

In order to activate a config, ln -s the chosen config file to firmware/src/config.h

Spacelock: common questions

What microcontroller does the Spacelock use?

The Spacelock is built around the ST STM32F103C8T6, from the STM32 family.

How big is the Spacelock PCB?

The Spacelock measures 79.9 × 68.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spacelock?

102 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spacelock design files?

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

Can I use the Spacelock design in my own project?

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

Can I test firmware for the Spacelock 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.
