Based on Raspberry Pi 40PIN GPIO interface design, suitable for Raspberry Pi series motherboards and Jetson Nano Adopts MCP2515 and SN65HVD230 dual-chip combination solution to support 2-way CAN interface communication Onboard integrated power isolation provides stable isolation voltage. No additional power supply is required at the isolation end. Onboard digital isolation chip makes signal isolation communication safer, more stable and more resistant to interference On-board external terminal block power supply, supports 7~36V wide voltage power supply, can power the Raspberry Pi and expansion board at the same time, on-board SM24CANB (transient voltage suppressor tube), anti-static and transient spike voltage Onboard level conversion circuit, 3.3V/5V working level can be switched through jumper cap Colour:blue Material:PCB Package Contents: 1 x Expansion Board 1 x Screw Pack Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
