The VulCAN (Copperforge USB CANbus Adapter) is a small, low-cost open-hardware USB to CAN adapter ("dongle") for automotive, industry, and hobby applications. It works with Linux, Windows, and Mac, and enumerates as either a virtual serial port, acting as a serial to CAN interface, or as a native CAN device. We developed this device for internal testing of our CANbus motor controllers - alternatives had been out of stock for a long time, and we decided to make some upgrades. The VulCAN has been modernized with USB-C support, has improved durability and usability by removing jumpers with switches and adding transient voltage suppression, and we've added breakaway mounting holes so that it can be permanently mounted inside of test fixtures. We are capable of bulk production. For large orders, or any other questions or comments, please contact us via email. Designed and assembled in the USA! Features USB-C 2.0 connector for compatibility with modern laptops and durability ESD/Transient voltage protection on USB and CAN interfaces Breakaway mounting holes for mounting inside devices and enclosures 1.25" x 1" (31.75mm x 25.4mm) hole pattern No pesky jumpers to misplace and lose! 4-pin screw terminal with 5V output (VUSB), GND, CANH, CANL Duplicate 4-pin 0.1" female header for prototyping convenience Button for entering the bootloader Switch for enabling/disabling termination Internal oscillator Simple cross-platform Python library and supporting software (cantact-app, Cangaroo) Serial-line CAN (slcan) interface for Linux, Windows, and Mac with CANtact firmware Native Linux and enhanced Windows functionality with candleLight firmware Supports baud rates from 10 kbps up to 1 Mbps It implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication on the CANbus at data rates up to 1 Mbit/s, meaning that it is compatible with all cars which use CAN high-speed. The VulCAN is firmware-compatible with the CANtact and CANable projects, and uses one of two open-source firmware options: CANtact slcan-compatible (vulcan_fw_slcan) or candleLight (vulcan_fw_candlelight). Note: The VulCAN is a CAN high-speed device. If you are interested in an equivalent CAN low-speed device, please let us know.
