Package Contents

• 1 × SparkFun Teensy 4.1 Development Board (DEV-16771)

Note: The DEV-16771 version does not include pre-soldered header pins. USB cable, Ethernet connector kit, memory expansion chips, microSD card, and external accessories are sold separately unless otherwise specified.

Additional Information

The Teensy 4.1 uses 3.3V logic and its digital I/O pins are not 5V tolerant. Appropriate voltage-level shifting is required when interfacing with 5V logic devices.

Although the board includes an Ethernet PHY, it does not provide a ready-to-use onboard RJ45 Ethernet connector. An appropriate Ethernet connector kit must be installed for wired Ethernet connectivity.

The USB host interface also requires compatible connector hardware for attaching external USB devices.
