The electronics of the eBike III are based on a modular
concept.
Each module has its own processor with appropriate
software.
To communicate between different modules, the CAN bus
is used, which is a stable and standardized protocol that is
used in the automotive industry.
The connection between different modules is made by
direct adaptation of the different PCBs or by use of
standard shielded CAT-5 patch cables.
The direct connectors and cables carry the power lines
(24 volt) and the CAN bus signal lines.
