This module fully supports CAN-FD (CAN Flexible Data-rate) in addition to CAN 2.0A and CAN 2.0B protocols. CAN-FD allows for higher data throughput and larger payload frames compared to classic CAN, making it ideal for modern automotive ECU development and industrial automation projects.\u003c\/p\u003e\n\u003ch4\u003eQ: What software is compatible with this CAN bus analyzer?\u003c\/h4\u003e\n\u003cp\u003eA: This module is designed to work with the open-source \u003cstrong\u003eCangaroo\u003c\/strong\u003e CAN protocol analysis software. It also presents itself as a standard serial device on Windows, macOS, and Linux, making it compatible with a wide range of CAN analysis tools that support virtual COM ports or USB-to-CAN adapters.\u003c\/p\u003e\n\u003ch4\u003eQ: Do I need an external power supply to use this module?\u003c\/h4\u003e\n\u003cp\u003eA: No external power supply is required. The module is powered entirely via the Type-C USB port at 5V, drawing power directly from your computer's USB port.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I update the firmware on this CAN module?\u003c\/h4\u003e\n\u003cp\u003eA: Firmware can be updated in two ways. You can use the web-based firmware update method for a hassle-free over-the-air-style update, or you can short the BOOT pad before inserting the Type-C cable to enter BOOT mode and re-flash the firmware manually using standard STM32 flashing tools.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the purpose of the 120Ω termination resistor jumper?\u003c\/h4\u003e\n\u003cp\u003eA: In a CAN bus network, both ends of the bus are required to have a 120Ω termination resistor to prevent signal reflections and ensure reliable communication. The onboard jumper allows you to easily enable this resistor when the module is placed at one end of the CAN bus — no external resistor needed.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does this USB to CAN module support CAN-FD (Flexible Data-rate)?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
