Description

Welcome back to Dev Odyssey! In this episode, we're harnessing the power of USB OTG to power and connect to our OpenWrt 21.02 Raspberry Pi, via serial and ethernet, all with one USB-C cable. Briefly, USB OTG allows your devices to switch between host and device mode, depending on the scenario. For example, it lets your phone act as USB host, when you plug in a flash drive, but also lets your phone act as a USB device, when you plug in your phone, to your computer. For the wanderlust developer who needs to pack light, OTG compliments their travel requirements. For those who despise cable clutter, OTG is also for you. The use cases are vast, from serial, ethernet, mass storage, use with a USB C Tablet, like an iPad, improved connection stability, and more. With all the possible combinations, you're only limited by the USB guest configurations available.

Best of all, USB OTG is not limited to Raspberry Pi or Raspberry Pi OS. So long as your device, or single board computer, has a USB OTG enabled port, and an operating system thats supports it, then you can reap the same benefits of USB OTG. Watch till the end to see two of the most useful examples of USB OTG configurations!
