Welcome to our store! This Raspberry Pi dual-channel CAN bus expansion board functions as a dual-channel isolated CAN bus expansion board with multiple protection circuits. Connects to Raspberry Pi series motherboards, based on the Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards. Adopts MCP2515 and SN65HVD230 dual-chip combination scheme, supports 2-way CAN interface communication. Built-in integrated power supply isolation, which can provide stable isolation voltage without extra power supply. Built-in digital isolation chip, signal isolation communication is safer, better stability, more powerful anti-interference. Built-in SM24CANB transient voltage suppression tube, anti-static and transient spike voltage. Built-in level conversion circuit can switch 3.3V/5V working level through jumper cap. Built-in 120Ω termination resistor, can be set to be activated through jumper cap. Leads out serial peripheral interface control interface for easy access to STM32 and other main control boards. Item Type: CAN Module CAN Controller: MCP2515 Supply Voltage: 5V CAN Transceiver: SN65HVD230 Logic Voltage: 3.3V/5V Communication Method: Serial Peripheral Interface Package Includes: 1 x CAN Module, 1 x for RPI double bag (2 pcs set), 1 x long row base 2 x 20PIN
