SPI to CAN FD SBC + LIN Transceiver BoosterPack User's
Guide
The SPI to CAN FD SBC + LIN BoosterPack™ features the TCAN4550-Q1 CAN FD controller with
integrated transceiver providing microcontrollers without an integrated CAN FD controller, or those
needing additional channels, access to CAN FD applications through a SPI interface. LIN applications can
also be developed using the TLIN2029-Q1 fault protected LIN transceiver and the MCU UART port
making this BoosterPack an ideal starting point for any CAN FD or LIN system.
