Product introduction:

This is a dual-channel CAN bus isolated expansion board specially designed for the Raspberry Pi. It supports CAN fd (CAN with flexible data rate),a variety of on-board protection circuits,strong anti-interference ability,and works.

Stable, suitable for automotive or industrial automation.

Features:

Not only support the traditional CAN 2.0 protocol,but also the CAN fd protocol. The data transmission rate is faster and the data throughput is greater.

Also have a variety of on-board protection circuits, including 500M lightning surge, static protection, short circuit protection and electrical isolation, making communication more secure and reliable.

Characteristics:

Based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards

Supports traditional CAN2.0 and CAN fd protocols

Lead out SPI control interface for easy access to main control boards such as STM32/for Arduino

On-board electrical isolation circuit, isolation voltage up to 5KV, good stability, stronger anti-interference

On-board lightning protection, anti-static and anti-short circuit protection

On-board level shifting circuit, which can switch the working level of 3.3V and 15V through a jumper cap

1200 termination resistors on board, can be set by jumper cap

Pinouts

Industrial-grade protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, AB signal line short-circuit and short-circuit protection with the power supply (short-circuit does not burn)

The transmission distance can reach 1200 meters (tested at 9600bps)

Support the baud rate of 921600, much higher than 115200, and use higher baud rate for paired mutual transmission. Multiple systems support hot swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/

WIN10/VISTA/LINUX/MAC OS X system, USB interface is hot-swappable

Automatically distinguish and control the data transmission direction, without any handshake signal (SORTS. DTR, etc.), mode conversion can be realized without jumper settings, ensuring compliance with existing communication software and interface hardware.

With TXD and RXD indicator lights
