This kit has all the parts needed to connect to the Ethernet port on Teensy 4.1.

This kit includes an Ethernet MagJack, bare circuit board, ribbon cable assembly, 2 header pins, and a capacitor. DIY soldering is required.

Assembling The Ethernet Kit

The first step is to solder the capacitor.

Next solder the header pins. After soldering 1 pin, turn the board over to check if the pins are at a right angle to the board. Once 2 or more pins are soldered, fixing crooked pins is almost impossible.

Last, solder the Magjack.
