MLAB hardware modules and building blocks
U3 MLAB ADAPTER is an open-source printed circuit board by MLAB-project, from the MLAB-project/Modules repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 50.3 × 25.8 mm with 22 parts on 12 nets, routed with 76 tracks and 0 vias.
It is built around the BAS85. Its parts include 18 connectors, 2 capacitors and 2 diodes. It belongs with the computers and single-board computers and sensors and measurement boards and the FPGA and CPLD boards of this library.
The MLAB Project was created to develop an universal kit to support hobbyist and professionals in the construction of simple or more complicated devices and instruments (robots, automation systems, testing kits and so on). It is primarily intended for engineers and scientists and it is in continuous development since 2003.
This repository is archived because its contents have been split into separate repositories in the MLAB-modules organization. The development of new MLAB components is still in progress and development has not been suspended. You can read about the reasons of the repository split on the Discussions thread.
This repository is only a component of the complete MLAB system
The principle of Modular LABoratory is based on decomposition of complex systems into smaller cells or bricks (in MLAB called modules) such as communication interfaces, operational amplifiers, CPU modules, FPGA programmers and many other. Over years of development, tenths of modules have been created - for easier orientation they are sorted into categories which are the first-level folders of this repository. Many modules are included as repository submodules in this parent repository.
When creating modules, great emphasis is put on the quality of design and construction. The results can, therefore, meet the standards of even the most demanding users from the community of researchers, experimenters and innovators.
Further information can be found on MLAB Wiki.
There is also a Mailing list available for users and developers.
Thanks to careful design, most of the modules are dimensionally and electrically compatible with many other products. Examples include the Arduino platform, the Merkur construction set, optical tables and DIN switchboard systems.
See the list of designs for an illustration of the wide spectrum of possible applications.

It measures 50.3 × 25.8 mm and has 2 copper layers, 1.6 mm thick.
22 parts, built around the BAS85. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the MLAB-project/Modules repository on GitHub, at the commit this page was made from: the board is MCU_CPU/ARM/ODROID-U3/hw/sch_pcb/U3_MLAB_ADAPTER.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
