rack-ser-adapter is provided under the terms of the CERN-OHL-S license version 2 as provided in the LICENSES/CERN-OHL-S-2.0 file.
Instead of adding license boilerplates to the individual files, rack-ser-adapter uses SPDX license identifiers, which are machine parseable and considered legaly equivalent.
The SPDX license identifier in rack-ser-adapter shall be added at the first possible line in a file which can contain a comment. This is normally the first line except for scripts. Scripts require the #!PATHTOINTERPRETER tag in the first line; place the SPDX identifier into the second line.

Rack ser adapter tester: common questions
What microcontroller does the Rack ser adapter tester use?
The Rack ser adapter tester is built around the STM32F103C8T6, from the STM32 family.
How big is the Rack ser adapter tester PCB?
The Rack ser adapter tester measures 150 × 120 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Rack ser adapter tester?
126 components, from 33 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rack ser adapter tester design files?
From the eurovibes/rack-ser-adapter repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Rack ser adapter tester design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which eurovibes chose for the repository.
Can I test firmware for the Rack ser adapter tester 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.
