Install Raspberry Pi OS on microSD card

Download the latest version of Raspberry Pi Imager from here and install it.
Download Raspberry Pi OS Image 64 bit Raspbian Buster from here.
Install 64 bit Raspbian Buster with Raspberry Pi Imager on a microSD card.

Enable wifi and ssh

Create a file named wpa_supplicant.conf in the boot directory of microSD card.
Open it with a text editor and write the followings. Make sure to replace the wifi name and password of your network.

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev 
update_config=1


network={
        ssid="wifi_name"
        psk="wifi_password"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
        id_str="phone"
        priority=9
}

Create a file named ssh in the same boot directory and keep it blank.

Boot Raspberry Pi

Insert the microSD card to Raspberry Pi.
Download PuTTY from here
Open Putty with host name raspberrypi
Login as pi
Password raspberry

Enable ARM I2C Interface

Run following command in PuTTY.

sudo raspi-config

Select Interfacing Options, select I2C and set Yes
Press Tab and select Finish

Setup Jupyter Lab

Run following commands in PuTTY.

sudo apt install git -y
cd ~ && git clone https://github.com/ANI717/headless_raspberrypi_setup
cd ~/headless_raspberrypi_setup/jupyter_setup
chmod +x jupyter.sh && ./jupyter.sh [password]
