Connecting the EPD to the EXT4

There are two ways of connecting the EXT4 to the Arduino Nano Matter:

Option 1: Connecting your Arduino Nano Matter through cable

EXT4 side

Pin 1 of EXT4 board aligns with the 1^st pin (black wire) of bridging cable.\ Pin 20 of EXT4 board aligns with the 20^th pin (white wire) of bridging cable.

Arduino Nano Matter side

Option 2: Connecting your Arduino Nano Matter through adapter board

Look for the white mark on the “EXT4 side” of the adapter board and on the EXT4. They should align when mating the two.

Notice also that the USB side of the board is aligned with the Arduino Nano Matter USB.
