We need to remove the breadboard and jumper wires and create printed circuit board (PCB) with an equivalent circuit. This expansion PCB will connect to BeagleBone via the P8 and P9 expansion headers. It will work as a plugin daughterboard for BeagleBone. This type of expansion board is called a cape. A cape for BeagleBone is similar to what a shield is for Arduino. This naming suits it because it looks like a cape around the Ethernet port when plugged in. BeagleBone comes with less peripherals on the board.
