USB to CAN Adapter Model A – STM32 Chip Solution, Multi-System Compatible

Product Description

The Waveshare USB to CAN Adapter Model A is a powerful and reliable interface for connecting a computer to a CAN (Controller Area Network) bus. Based on the STM32F103 microcontroller, it ensures stable and efficient communication for data acquisition, monitoring, and transceiver control.

Supporting CAN2.0A (standard frame) and CAN2.0B (extended frame), this adapter is ideal for automotive diagnostics, industrial control, and embedded system development. With configurable CAN baud rates (5Kbps–1Mbps), multiple working modes, and cross-platform compatibility with Windows and Linux (including Raspberry Pi OS & Jetson Nano), it offers both flexibility and reliability.
