A Controller Area Network (CAN) is a high-integrity asynchronous serial bus system for networking intelligent devices. It is often used in automotive and industrial systems.The USB-2CAN-SI-M is designed to make a fast, simple way to communicate with CAN bus devices. Connected to a USB port on your computer or USB hub, the USB-2CAN-SI-M instantly adds two industrial CAN bus channel to your host system with easy plug and play (PnP) and hot plug features. The USB-2CAN-M provides a cost-effective solution for customers to enable communication with CAN bus devices. The solution designed by ARM Cortex-M0 32-bit microcontroller and the USB to serial chip makes it very flexible in handling small burst of CAN frames at a high speed. The USB-2CAN-SI-M has 2500V galvanic isolation on its CAN bus. The galvanic isolation protects your computer by preventing spikes and surges from crossing over to your computer.
