SparkFun Ethernet Kit for Teensy 4.1
Overview
The DEV-18615 is a hardware expansion kit designed to enable the 10/100 Mbps Ethernet capabilities of the Teensy 4.1 microcontroller board. It provides the necessary physical layer components, including an RJ45 connector and magnetic jack, to bridge the Teensy's onboard Ethernet pins to a standard network cable. This kit allows engineers to leverage the high-speed processing of the NXP i.MXRT1062 for networked applications without custom PCB fabrication.
Why Choose This Part
The kit provides a complete hardware solution that matches the Teensy 4.1's specific pinout, ensuring reliable signal integrity for 10/100 Mbps communication. It includes a ribbon cable and a breadboard-friendly breakout, making it easy to integrate into prototypes while maintaining a compact footprint.
Applications
Getting Started
To use this kit, solder the included header pins to the Ethernet pads on the Teensy 4.1 and connect the ribbon cable to the RJ45 breakout board. Software implementation is supported by the NativeEthernet library within the Arduino IDE (Teensyduino), which allows for standard socket-based programming. Ensure your power supply can handle the additional current draw of the Ethernet PHY and active network link.
