SBC-D23 board can offer a single CAN Bus duplicated on two connectors, in order to connect directly
to two devices simultaneously using the same Bus.
The CAN Bus controller is programmed inside the on-board microcontroller, while the physical interface
comes through a High-Speed CAN transceiver, type NXP TJA1051, which offers also improved EMC and ESD
performances.
The two CAN Bus Connectors are 4-pin Micro-fit 2x2 connector type Molex 43045-0424 or equivalent, as shown in
the figure.
