Twin RJ45 Breadkout Board


This module is designed to ease the twisted pair cable wiring for our differential I2C extender and it could be used as a RJ45 breakout board, too.

Technical Details


As shown in the picture above, two RJ45 connectors are patched together in parallel, and each of the 8 pins are broke out to P3. 3x2pin 2062 connectors are broke out to P1. The six pins(A,B,C,D,E,F) of 2062 connectors are connected to seven(J1, J2,J3,J4,J5,J6,J7) of the eight pins of the parallel RJ45 connectors via 0ohm 1206 surface mount resistors.

To use as a RJ45 breakout board, user should unmount all the 0ohm resistors and use the P3 to connect his/her device.
