Introduction In this guide, we'll configure a Raspberry Pi 4 to be powered and accessed directly through a single USB-C cable connected to an iPad or laptop. This setup creates a portable, headless Raspberry Pi that requires no separate power adapter, HDMI display, keyboard, or Ethernet cable. Perfect for mobile development, testing, or working with your Pi on the go. Objective Our goal is to create a fully functional Raspberry Pi 4 setup that can be accessed via a single USB-C connection. We'll accomplish this by: Using Raspberry Pi Imager to customize Pi OS Lite (64-bit) with SSH and WiFi credentials Burning the configured image to an SD card SSH into the Pi via WiFi for initial configuration Updating boot configuration files to enable USB gadget mode Creating a new network connection using nmcli and activating it on boot Connecting the Pi to an iPad or laptop using only a USB-C cable Hardware Requirements To complete this setup, you'll need: iPad or laptop wi...
