| CAN Physical layer is defined by ''ISO 11898'' therefore to connect [[litesom:about|liteSOM]] to CAN bus it is required to use external CAN Bus Transceiver like [[http://www.ti.com/product/SN65HVD230|SN65HVD230]] used on on [[litesom:serials|RS485/CAN extension board]]. | CAN Physical layer is defined by ''ISO 11898'' therefore to connect [[litesom:about|liteSOM]] to CAN bus it is required to use external CAN Bus Transceiver like [[https://www.ti.com/product/SN65HVD230|SN65HVD230]] used on on [[litesom:serials|RS485/CAN extension board]]. |
