Product Description
Free Shipping Within the United States!
At the heart of the converter is the Teensy 4.0, powered by the NXP i.MX RT1062 ARM Cortex-M7 processor running at 600 MHz. This microcontroller boasts:
- 1 MB of RAM (with 512 KB tightly coupled for high-speed access)
- 2 MB of Flash memory
- Dual 480 Mbps USB ports
- Multiple I/O interfaces, including SPI, I2C, UART, PWM, and ADC
- Cryptographic acceleration and a random number generator
- Real-time clock (RTC) support
Programming is facilitated through the Arduino IDE with the Teensyduino add-on, ensuring compatibility with a wide range of Arduino libraries and examples.
MCP2558FD CAN FD Transceiver
The MCP2558FD transceiver from Microchip Technology enables high-speed CAN FD communication up to 8 Mbps. Key features include:
- Compliance with ISO 11898-2:2016 standards
- Support for both Classical CAN and CAN FD protocols
- Silent mode operation for passive monitoring
- Enhanced ESD protection
Silent mode can be activated via software or a hardware link, allowing the device to monitor CAN traffic without influencing the network.
Interface Details
CAN FD Interface
The converter connects to CAN networks through a DB9 connector, configurable for OBD-II or CAN analyzer pinouts. This flexibility ensures compatibility with various automotive and industrial CAN applications.
USB Interface
The high-speed USB interface (480 Mbps) facilitates rapid data transfer between the CAN network and a host computer. The converter utilizes the Lawicel protocol, employing simple ASCII commands for communication, making it accessible for developers and engineers.
Additional Features
- RGB LED indicator for status monitoring
- Compact design for easy integration into existing systems
- Free shipping within the United States

Demo Sketch
The demo sketch (see download link above) uses the FlexCAN library, and it represents a serial protocol for communication between the gateway and an external system, for instance, a PC. The protocol is based on the ASCII commands developed by LAWICEL but extended to accommodate CAN FD.
The protocol uses ASCII commands to set the CAN baud rate, transmit CAN Bus data frames, and more. They are documented in the above download referenced download page (github).
