Teensy 4.1 Without Ethernet Development Board
The Teensy 4.1 Without Ethernet is a high-speed microcontroller board for advanced electronics, robotics, audio, control, data logging, and embedded projects. It is powered by a 600MHz ARM Cortex-M7 processor and gives you much more speed, memory, and I/O than many standard hobby boards.
This version keeps the core power of the Teensy 4.1 but removes the Ethernet PHY. It is a good choice for projects that do not need wired network support but still need fast processing, a microSD socket, USB host support, many I/O pins, and strong real-time performance.
Why Choose Teensy 4.1 Without Ethernet?
- Fast 600MHz ARM Cortex-M7 processor for demanding projects.
- 8MB flash and 1024K RAM for larger programs and data buffers.
- Built-in microSD socket for fast data logging and storage.
- USB host port support for selected USB devices.
- 55 total I/O pins, including 35 PWM-capable pins.
- Good for audio, robotics, lighting, controls, and sensor projects.
- Lower-cost option when Ethernet is not needed.
What You Can Build
- Fast sensor logging system
- Robotics controller
- Audio processing project
- USB host device project
- LED and pixel control system
- CAN bus test project
- Motor and motion control project
- High-speed serial communication project
- MicroSD-based data recorder
- Advanced Arduino IDE-compatible embedded project

Power and Wiring Notes
Teensy 4.1 uses 3.3V logic. Do not connect 5V signals directly to its pins. Using 5V input signals may damage the board.
The board can be powered through USB for basic testing. When using external power through VIN, do not apply VIN power while USB is also connected unless the VUSB-VIN trace has been properly separated.
Important Notes
- This version does not include Ethernet support.
- Headers are not included.
- Use 3.3V-safe sensors and modules.
- Use a compatible USB cable for programming.
- Install Teensy support in Arduino IDE before uploading code.
Recommended Add-ons
- Teensy boards and accessories
- Pins and headers
- Sensors and modules
- MicroSD cards and storage
