Connect Raspberry Pi w/ iPad Pro over USB

An Ansible playbook to enable ethernet + power over USB

The Raspberry Pi is an amazing device and the ability to play with it remotely with the iPad (over ssh) wherever I am, is super convenient. But there are some scenarios where either the network is not available or there isn’t a ethernet cable available(for the Zero) or sometimes there’s no free socket to draw power from.

Turns out, you don’t necessarily need all that! I recently found out that it is possible to configure a Raspberry Pi to be used over a single USB cable. No need for power cable, no need for ethernet cable, just a single USB cable.

The configuration for the Raspberry Pi Zero is pretty straight forward:

Raspberry Pi Zero

  • Flash the latest version of Raspberry Pi OS to a microSD card.
  • Create an empty file called ssh, no extension, just ssh.
  • On your computer, open the boot partition.
  • Open the config.txt file and add dtoverlay=dwc2 as a new line.
  • Open the cmdline.txt file and insert modules-load=dwc2,g_ether after rootwait. This is a one-line file, don't add new lines or spaces.

After this, you can simply connect your Raspberry Pi Zero to the iPad Pro, it will be detected as an ethernet interface and you can connect via ssh using raspberry.local as the address.

Raspberry Pi 4

The configuration needed to use the Raspberry Pi 4 over USB-C is a bit more complex. Since USB is not directly connected to the processor -as in the Zero-, we can’t just make the changes on the microSD card on the computer, we need to do it directly on the Pi.

I’ve set up a Ansible playbook (Repo here) in order to make this process a bit easier, so here you’ll find instructions on how to use this playbook.

Ansible is a software tool that provides simple but powerful automation for cross-platform support. In this project I used it to automate all the steps required to configure the Raspberry Pi 4.

Warning: This playbook modifies your boot config, make sure you don’t run this anywhere you can’t reformat and re-flash.

I rarely use a display and keyboard with my Raspberry Pi, I prefer to do everything over ssh/vnc while connected to a network, so this guide will assume you will be doing the same.

  • Flash the latest version of Raspberry Pi OS to a microSD card.
  • You need to enable ssh on the Pi, for this, create an empty file called ssh in the root directory of the boot partition, no extension, just ssh.
  • Insert the microSD card to and connect your Pi to boot it up and access it via ssh.
  • Install Ansible and Git: sudo apt update && sudo apt install -y python3-dev python3-pip libyaml-dev libffi-dev git && sudo pip3 install --no-binary pyyaml ansible
  • Clone this repository to your Pi git clone
  • Open the repo directory: cd raspberry-pi-usb-network
  • Run the Ansible playbook: ansible-playbook main.yml
  • After installation finishes, shut down the Pi: sudo shutdown -h now

After this, you can simply connect your Raspberry Pi 4 to the iPad Pro and connect via ssh using raspberry.local or as the address.

In case you’d rather configure this manually, you can find instructions on the post I used to figure this out: Ben Hardill’s Blog.


Being able to use the Raspberry Pi with the iPad Pro using a single cable is pretty useful for me, since it opens the possibility to move around easily and not having to think about power/network all the time.

Hopefully this will be helpful for anyone looking to do the same, feel free to reach out if you have ideas on how to improve this process.
