The Teensy 4.1 Triple CAN Bus Board with 240x240 IPS LCD is a powerful, compact development platform engineered specifically for high-performance Controller Area Network (CAN) applications. Featuring two independent Classical CAN 2.0B interfaces and one CAN FD (Flexible Data-rate) interface, this board is ideally suited for advanced development in automotive diagnostics, industrial automation, and maritime electronics.

This board is built around the Teensy 4.1, a compact, Arduino-compatible microcontroller board powered by a 600 MHz Arm Cortex-M7 processor, making it one of the fastest microcontroller platforms in its class. Despite its small footprint (approx. 18 x 36 mm), the Teensy 4.1 delivers robust performance with 1 MB of RAM, 2 MB of Flash memory, a hardware floating-point unit (FPU), cryptographic acceleration, and a real-time clock (RTC).

Whether you're developing real-time communication between electronic control units (ECUs) in a car, integrating industrial PLCs, or simulating NMEA 2000 traffic for a marine network, this board delivers the flexibility and performance needed for rigorous CAN and CAN FD application development.

Key Features:

• Teensy 4.1 microcontroller (pre-installed)

  • Arm Cortex-M7 @ 600 MHz

  • 1 MB RAM, 2 MB Flash

  • Hardware FPU and cryptographic acceleration

  • Real-Time Clock (RTC)

• Triple CAN Bus Support

  • Two CAN 2.0B (Classical CAN) interfaces – perfect for backward-compatible systems

  • One CAN FD interface – supports high-speed data transfer (up to 64-byte data frames)

  • All CAN ports are fully isolated and terminated with 120 Ohm resistors

• Power Supply & Protection

  • Onboard voltage regulator supports input from 7V to 12V DC

  • Reverse polarity protection ensures reliable field use

• Visual Feedback & GUI Development

  • Integrated 1.54" 240x240 IPS TFT LCD display

  • Wide viewing angle – ideal for monitoring bus traffic or creating custom interfaces

Why Choose This Board?

This development board is designed for professionals and engineers who require a high-performance, low-latency embedded system for CAN Bus prototyping and diagnostics. Its seamless integration with the Arduino IDE and libraries ensures rapid development with minimal learning curve, while its triple CAN capability allows you to test and bridge multiple CAN networks simultaneously — a critical feature in modern automotive, industrial, and marine systems that often combine legacy and modern network infrastructures.

Additionally, the presence of CAN FD support opens the door to next-generation applications, such as over-the-air firmware updates, high-speed sensor data streaming, and secure vehicle communications.
