USB to MCP2551 CAN Isolated Module
USER MANUAL VER: 1.1
1. Overview
This module is designed to convert USB data to CAN bus signals while providing galvanic isolation, ESD protection, and noise immunity. It integrates the FT232RL USB-to-UART bridge, the MCP2551 CAN transceiver, the digital isolator, and the ESD protection diode to ensure robust and reliable CAN communication.
