BOOSTXL-CANFD-LIN CAN4550-Q1 CANbus 接口 LaunchPad评估扩展板

　　Introduction

　　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.

　　This user's guide describes features of the SPI to CAN FD SBC + LIN BoosterPack, explaining the board hardware details, functions and locations of jumpers and connectors.
