Enable SSH and SSH over USB

Pre-configure WiFi

In order to instruct Raspbian to connect to a specific hotspot after the setup add a file named wpa_supplicant.conf to the root of the SD card with the following content:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=<TWO_LETTER_ISO_COUNTRY_CODE>

network={
    ssid="<WIFI_NETWORK_NAME>"
    psk="<WIFI_PASSWORD>"
    key_mgmt=WPA-PSK
}

Enable SSH

Just add a file named "ssh" at the root of the SD card

$ touch ssh

Enable SSH and SSH over USB

(on Raspberry Pi model zero and model A)

On a freshly burned Raspbian image:

1. Append the following line to config.txt:

dtoverlay=dwc2

2. Append the following parameter to cmdline.txt by adding a space after the last parameter and adding:

modules-load=dwc2,g_ether

3. Add a file named "ssh" at the root of the SD card:

$ touch ssh

Power on the device connecting the pc to the micro USB port labeled "USB", wait for the Raspberry to start up, then SSH into it:

$ ssh [email protected]
