\chapter{Licensing}
|
|
\label{ch:licensing}
|
|
|
|
DigiRadio is dual-licensed, with hardware and firmware under separate but
|
|
compatible open-source licences.
|
|
|
|
\section{Hardware}
|
|
|
|
The hardware --- schematics, PCB layout, Gerbers, and bill of materials
|
|
--- is licensed under the \textbf{CERN Open Hardware Licence Version~2,
|
|
Strongly Reciprocal (CERN-OHL-S v2)}. Anyone who modifies and distributes
|
|
the hardware must release their changes under the same terms.
|
|
|
|
\section{Firmware}
|
|
|
|
The firmware is licensed under the \textbf{Apache License 2.0}. It grants
|
|
patent rights explicitly and pairs naturally with the ESP-IDF ecosystem,
|
|
which is Apache-licensed as well. Every source file carries the Apache
|
|
header with an SPDX identifier.
|
|
|
|
\section{Documentation and project pages}
|
|
|
|
Where a hosting platform does not offer the CERN-OHL-S licence in its
|
|
selector, the closest share-alike option is used for that page, with the
|
|
authoritative licence stated as CERN-OHL-S v2. The definitive licensing
|
|
is always the one declared in the project repository.
|
|
|
|
\section{Third-party components}
|
|
|
|
The design integrates third-party silicon (Silicon Labs, Analog Devices,
|
|
Espressif, Feasycom/Qualcomm) whose datasheets, firmware images, and DSP
|
|
tools remain subject to their respective vendors' terms. Those terms are
|
|
unaffected by the DigiRadio licences and must be observed when
|
|
redistributing vendor-supplied binaries.
