Adafruit TS3USB30 1 to 2 USB Switch

The Adafruit TS3USB30 is a 1-to-2 USB switch breakout board that lets you connect one of two USB peripheral devices to a single USB host port. Based on the TI TS3USB30, it handles high-bandwidth USB 2.0 connections up to 480 Mbps — ideal when you need to switch between two USB devices without using a hub.

The upstream connection can be made via the onboard USB Type-C port or breakout pads. Two sets of power/ground/D+/D– breakout pads on either side connect to your USB peripherals. A single select pin (S) switches between port 1 (low) and port 2 (high), and an output enable pin can disconnect both.

Key Features

  • 1-to-2 USB Switching – Connect one of two USB peripherals to a single host at a time
  • USB 2.0 High Speed – Supports up to 480 Mbps bandwidth
  • USB Type-C Upstream Port – Plus breakout pads for direct wiring
  • Simple GPIO Control – S pin selects port 1 or 2; Output Enable pin disconnects both
  • Onboard 3.3V Regulator – Powered from 5V USB with a disableable green power LED
  • Four Mounting Holes – For secure installation
  • Breadboard-Friendly – Header strip included (note: breadboard use may limit speeds to 12 Mbps)
Note: Only data lines are switched — power is not. Both peripherals remain powered during switching. Solid-state devices (e.g. FT232, USB sticks) handle this well, but microcontrollers may not re-enumerate automatically. In that case, reset the device via its own Reset or Enable pin when switching.

Ideal For

  • Switching between two USB peripherals without a hub
  • Embedded systems with multiple USB devices sharing one host port
  • Test fixtures that need to swap USB connections programmatically
  • Projects requiring GPIO-controlled USB routing

Package Contents

  • 1× Adafruit TS3USB30 1-to-2 USB Switch Breakout (fully assembled)
  • 1× Header strip
