The devices used in the testbed are:
- as far as possible open source
- the software can be changed
- cheap
The ordering and also the assembly is structured in three parts.
The regular components can be ordered from e.g. Amazon and Fischertechnik. The shopping card can be found on the bottom of this README.
For the remote IOs STM32F767 development boards with a custom shield is used. The necessary components and instructions can be found here.
Optionally, if you do not want to mount the devices on e.g. a wooden plate, you can print a 3d case like introduced here.
