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-CAN-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-CAN-SI-M instantly adds an industrial CAN bus channel to your host system with easy plug and play (PnP) and hot plug features.

The USB-CAN-SI-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.

Product Manual


USB to CAN Driver


TITAN’s CAN application programming interface (API) is written in C/C++ and compiled into a DLL file. This DLL allows users to easily create programs to control our CAN products using simple, easy to understand functions. It uses the stdcall calling convention, allowing a large number of high-level languages to import the DLL without incompability problems.


Set the USB to CAN adapter to work in high speed (3Mbits).

Instructions for use



CanFestival project is an open source CANopen multi-platform framework.
