This is a Teensy 4.1 board with triple CAN connections, two CAN 2.0B and one CAN FD, and ethernet magjack. It can be powered by an external +12 VDC with reverse voltage protection. Included is also a 240x240 wide angle IPS TFT LCD display.

The Teensy 4.1 is an Arduino-compatible board with an Arm Cortex-M7 microcontroller running at 600 MHz. The board is compatible with the Arduino IDE and the Arduino library. In most cases, code written for another Arduino board works with a minimum of changes on a Teensy. As the name implies, the board is tiny. For example, the current form factor is only about 18 by 36 millimeters. However, do not let the size mislead you; these boards pack a ton of functionality. For example, the new Teensy 4.1 features a megabyte of RAM, two megabytes of Flash, a bevy of I/O options, cryptographic support, a hardware floating-point processor (FPU), and a built-in real-time clock (RTC).


  • Teensy 4.1 (installed)
  • Onboard voltage regulator (Input voltage range 7 VDC to 12 VDC)
  • Reverse supply voltage protection
  • 120 Ohm termination resistors
