  • Supports Windows XP through 11 and Linux systems

USB-to-CAN Adapter with STM32F103

This adapter connects a CAN bus to a PC through a USB port using the STM32F103 chip. It targets engineers and developers who need to monitor, analyse or control CAN networks from a Windows or Linux host. The device suits automotive diagnostics, industrial automation and embedded development workflows.

Upgrade from basic USB-to-serial bridges

The adapter replaces simple serial converters that cannot handle CAN protocols directly. It becomes worthwhile when configurable baud rates between 5 kbps and 1 Mbps are required, or when multiple operating modes such as normal, loopback, silent and silent loopback simplify testing and integration.

Suits developers needing multi-OS CAN access

The product fits users who work across Windows XP through 11, Raspberry Pi OS and Ubuntu on Jetson Nano platforms. It is not intended for buyers who require galvanic isolation, higher-speed CAN FD support or standalone logging without a host computer.
