How to set up the Raspberry Pi Zero W with SSH and Wifi

Download Raspbian

Use etcher to flash the image to SD.

Prepare the SD Card

• Mount the SD and $ cd /Volumes/boot/
• $ touch ssh to enable ssh server on the PI
• Edit cmdline.txt, add modules-load=dwc2,g_ether after rootwait
• Add the following to config.txt:

# Enable OTG
dtoverlay=dwc2

• Safely eject the sd card. On Mac: $ diskutil eject /Volumes/boot

• Connect the innermost USB port to the USB on your host.

• Wait ~90 sec

• Connect via $ ssh pi@raspberrypi.local. Password is raspberry

Setup Wifi

Note that the Zero W only supports 2.4 Ghz networks.

# cat /etc/wpa_supplicant.conf

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

# AES
network={
 ssid="<SSID>"
 psk="<PASSPHRASE>"
 proto=RSN
 key_mgmt=WPA-PSK
 pairwise=CCMP
 group=CCMP
 auth_alg=OPEN
}

Automatically connect via wpa_supplicant and obtain an IP:

# cat /etc/network/interfaces
auto lo

iface lo inet loopback

allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
