Arduino Nano Expansion Shield audio Raspberry Pi 4 Aluminum HeatsinkIntroduction : This shield is designed for Arduino Nano, you can make Arduino Nano's pins layout same as standard shield's easily. Theredore you can use Arduino Shields with Nano. Arduino pins are in 3 pin format (GND 5V Signal) so sensors and various input and output can be connected easily. Reset pin is carried on board and DC adapter input is 2. 1 mm centre positive input just like other Arduino boards. 5V, 3. 3V and GND power pins are multiplied
