1. Support CAN bus connection, long data transmission, strong anti-noise , strong real-time performance and high reliability 2. The surface of the PCB adopts the immersion gold process 3. TYPE-C port ESD protection to prevent static electricity from damaging hardware 4. Support firmware update for the master through SWD or hardware DFU 5. CAN interface Introduction of : is a USB to CAN bus module, which can convert the USB port of to the CAN bus, and connect 3D printing motherboard, EBB35/36/42 CAN and other products through CAN bus. There are many different forms of CAN interfaces on the board, which are helpful to connect to different boards. CAN bus has many advantages in of industrial control, so company has launched this USB to CAN module. The CAN bus has a long transmission distance, and a number of nodes can be mounted on it, so the motherboard, EBB, and other expansion boards can be mounted on the same CAN bus at the same time. The difference between V1.0 and V2.1: V1.0 has 1 CAN OUTPUT, V2.1 has 3 CAN OUTPUT Colour:black Material:PCB+electronic accessories Package Contents: 1 x USB to CAN bus module 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.
