Basic Configuration

Wireless connection and SSH

1. Create a file called "wpa_supplicant.conf" into the /boot folder, and copy the following code.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev


The Wi-Fi name and password should be the same as your local Wi-Fi which your PC connected to(make sure your PC and Raspberry Pi are in the same LAN).

2. Create a blank file called "ssh" into the /boot folder.

3. Insert the SD Card with Raspberry Pi OS into the Raspberry Pi.

4. Connect the Raspberry Pi to the power source and power it up.

5. Open putty to connect PC to Raspberry Pi.

Download putty:
