It connects to your computer via a Type-C USB port and enumerates as a virtual serial port, providing a clean serial-line interface to the CAN bus. It supports CAN2.0A and CAN2.0B protocols with baud rates up to 1 Mbps, making it ideal for 3D printing (Klipper), robotics, and CAN bus development.\u003c\/p\u003e\n\u003ch4\u003eQ: Which firmware does this USB CAN adapter support?\u003c\/h4\u003e\n\u003cp\u003eA: This adapter is compatible with \u003cstrong\u003eCAnable\u003c\/strong\u003e, \u003cstrong\u003eCandleLight\u003c\/strong\u003e, and \u003cstrong\u003eKlipper\u003c\/strong\u003e firmware. It includes a bootloader jumper so you can easily switch or update firmware as needed for your specific project or workflow.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I connect this adapter to my CAN bus network?\u003c\/h4\u003e\n\u003cp\u003eA: Simply connect your CANH, CANL, and GND wires to the onboard 3-pin screw terminal (clearly labeled). Plug the Type-C USB end into your computer, and the device will enumerate as a virtual serial (COM) port. The onboard 120Ω termination resistor is enabled by default and can be disabled via jumper if your network already has termination at both ends.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the UCAN adapter compatible with Klipper 3D printer firmware?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The UCAN adapter is fully compatible with Klipper firmware, making it a popular choice for 3D printer toolhead boards and multi-MCU Klipper setups that use CAN bus for communication.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the UCAN USB to CAN Adapter and what does it do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The UCAN is a small, low-cost, open-source USB to CAN bus adapter based on the STM32F072 microcontroller.
