Dual CAN interface with independently configurable baud rates
CANnect Intelligent and Configurable CAN-to-CAN Bridge
Real-time bidirectional CAN adapter, two FDCAN interfaces, independent baud rates, per-channel transformation rules — fully GUI-configurable, no firmware coding required.
OVERVIEW
A CAN gateway that thinks
CANnect is a miniaturized CAN gateway powered by an STM32 microcontroller with dual independent FDCAN interfaces, designed to integrate CAN bus devices with different configurations, baud rates, or message IDs — without any hardware modifications.
With native DBC file support, CANnect interprets and manipulates CAN traffic in real time: translating protocols, applying filters, scaling, and lookup tables on individual channels. It acts as an intelligent bridge between heterogeneous CAN networks in automotive, motorsport, and industrial applications.

CANnect: Our Customers' Questions
How is CANnect configured, and do I need programming skills?
CANnect is configured entirely through an intuitive desktop application with a graphical interface — no coding or scripting required. You simply load your DBC files, define the mapping rules between the two CAN interfaces, and deploy the configuration to the device. The entire process takes minutes, not hours.
Can CANnect work with my existing CAN network without modifications?
Yes. CANnect supports standard baud rates from 125 kbps to 1 Mbps on each of its two independent FDCAN interfaces, and it can bridge networks running at different speeds or protocols. It connects inline with your existing CAN bus wiring, so no changes to your current hardware or ECU firmware are needed.
How small is the CANnect board, and how is it installed?
The CANnect PCB measures just 35 x 12 mm, making it one of the smallest CAN bridge devices available. It accepts a wide supply voltage range of 9-28V and draws only 21 mA typical current, so it can be powered directly from the vehicle or machine power rail and installed in extremely tight spaces such as engine bays or behind dashboards.
How do I update the CANnect firmware over the CAN bus?
Firmware updates are delivered directly over the CAN bus using a dedicated utility included with the configuration software. You connect to the device, select the new firmware image, and the update is applied automatically. This ensures your CANnect units always run the latest features and improvements without any hardware disassembly.
