Based on 40pin GP10 interface, applicable for series motherboardCAN function, using SPI interface CAN controller MCP2515, with transceiver SN65HVD230It has RS485 function, uses UART control, half duplex communication, supports automatic switching of transceiver status without program control, and the transceiver is SP3485The control interface is reserved to facilitate the control of other controllersOn board TVS (transient voltage suppression tube) and RS485 communication can effectively suppress the surge voltage and transient voltage in the circuit, and prevent- and static Working voltage: 3.3VCAN controller: MCP2515CAN transceiver: SN65HVD230485 transceiver: SP3485Pin functionINT: interrupt output: SPI chip signal: SPI clock inputMOSI: SPI data input: SPI data outputRXD: RS485 serial port receivingTXD: RS485 serial port transmission: RS485 transceiver settingType: Development boardFeature 1: CAN adapter boardFeature 2: expansion boardFeature 3: Modulecolor:BlackMaterial:PCBPackage Contents:1 x ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may the color of the item in the a little different from the real thing.
