Ethernet Kit for Teensy 4.1

Product Overview

The Teensy 4.1 is an incredibly powerful development platform, and one of its most compelling features is the built-in 10/100 Mbit Ethernet PHY (Physical Layer). However, the Teensy 4.1 board itself doesn't include the physical port to plug in a cable. This official kit from PJRC provides all the essential components you need to add a standard RJ-45 Ethernet port to your Teensy 4.1 and get your project on the network.

High-Integrity Connection

This kit is centered around the Ethernet MagJack connector. This is more than just a simple jack; it's a critical component that includes the necessary magnetic transformers and termination circuitry required for a stable, high-speed Ethernet connection. The included bare circuit board is designed to perfectly mount the MagJack and provide the connection points for the ribbon cable, ensuring signal integrity.

Please be aware that a Teensy 4.1 board is NOT included with this kit and will need to be purchased separately. Once assembled, the included ribbon cable makes it simple to connect the adapter to the dedicated Ethernet pins on your Teensy 4.1. This gives your Teensy 4.1 a reliable, high-speed wired network connection, perfect for robust IoT, data logging, and remote-control projects.

Note: Basic soldering is required to assemble this kit.
