CAN interface

Doc ID 024080 Rev 3

21/38

The cut trace options J6, J17, J18 and J19 has been put in the design of this board to select

the supply of the CAN transceiver between 5 V and 3.3 V. By this option is possible to

replace the ST L9616 High-Speed Transceiver mounted on board by default, with a different

transceiver that operates at 3.3 V.

Note:

Refer to Section Appendix D: Options placement for layout options placement.
