The Teensy 4.1 Without Ethernet Headers is a fast and compact microcontroller board built for projects that need more power than a basic Arduino-style board. It uses a 600MHz ARM Cortex-M7 processor, with 8MB Flash and 1024K RAM, giving it strong performance for advanced embedded projects.

This version comes with pre-soldered male headers, so it is ready for breadboard testing without extra soldering. It also removes the Ethernet PHY controller, making it a lower-cost choice for projects that do not need wired network support.

The board includes a built-in microSD card socket, USB host port, and many I/O options. It has 55 total I/O pins, 42 breadboard-friendly I/O pins, 35 PWM pins, 18 analog inputs, 8 serial ports, 3 SPI ports, 3 CAN bus ports, and native SDIO support.

It is a great fit for robotics, audio projects, data logging, motor control, sensor systems, LED projects, and other builds that need fast processing in a small board.
