Description
The Waveshare USB-CAN-B is a high-performance, industrial-grade dual-channel USB to CAN adapter and protocol analyzer designed for robust industrial automation and automotive diagnostic environments. Featuring a high-speed USB 2.0 interface (compatible with USB 1.1 and USB 3.0), it integrates two independent CAN bus channels with full electrical isolation and multiple protection circuits. Each channel operates independently without mutual interference, supporting two-way transmission and high-speed processing capable of reaching up to 8,500 frames/s per channel.
Engineered for mission-critical engineering applications, the adapter supports a configurable baud rate ranging from 10Kbps to 1Mbps with convenient baud rate calculation, auto-detection, and setup via the included configuration utility. It provides comprehensive protocol support including CAN 2.0A, CAN 2.0B, CANOpen, SAE J1939, DeviceNet, iCAN, and ISO 15765. Complete with drivers and software examples for mainstream development platforms across Windows and Linux (such as C++, C#, Python, LabVIEW, and Qt), it offers a complete, ready-to-deploy hardware and software solution for engineers and technicians.
