Based on 40pin GP10 interface, applicable for series motherboard CAN function, using SPI interface CAN controller MCP2515, with transceiver SN65HVD230 It has RS485 function, uses UART control, half duplex communication, supports automatic switching of transceiver status without program control, and the transceiver is SP3485 The control interface is reserved to facilitate the control of other controllers On board (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: 3.3V CAN controller: MCP2515 CAN transceiver: SN65HVD230 485 transceiver: SP3485 Pin function INT: interrupt output : SPI chip signal : SPI clock input MOSI: SPI data input : SPI data output RXD: RS485 serial port receiving TXD: RS485 serial port transmission : RS485 transceiver setting Type: Development board Feature 1: CAN adapter board Feature 2: expansion board Feature 3: Module color:Black Material:PCB Package Contents: 1 x Module Only 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. The measurement allowed error is +/- 1-3cm.
