This USB3 Power Switch is for USB3 and/or USB2 devices, please see our USB Power Switch listing if you're looking for our lower cost power switch which only supports USB2 speeds.

Control the power for a USB3 device from a button or GPIO output on an Arduino/Raspberry Pi/Pico/etc.

Functionality of the USB3 Power switch can be changed by adjusting the two solder jumpers on the PCB, there are two options available to order.

Logic Level

• ( "PU" solder jumper bridged closest to PCB edge, "OD" solder jumper bridged away from PCB edge )
• The USB Power Switch is normally OFF.
• EN is pulled low to ground.
• Applying a voltage >2V (20V max) to the EN pin turns the power switch on.
• Example: Connect GND (to GND) and EN (to a GPIO) of an Arduino/Raspberry Pi/Pico/etc., set the GPIO pin to be an output and set the pin high to turn the power on.
• Example: Connect the VBUS and EN pins of the power switch to a slide/toggle switch. When the connection is made by the switch, USB power will be turned on.

Open Drain

• ("PU" solder jumper bridged closest to PCB edge, "OD" solder jumper bridged closest to PCB edge)
• The USB Power Switch is normally OFF.
• EN is pulled high to VBUS.
• Using an open drain/open collector signal to pull the EN pin to ground will turn the power switch on.
• Example: Connect GND (to GND) and EN (to a 'Sinking output') on a Pimoroni Automation HAT. Turning the "sink" on will turn USB power on.
• Example: Connect the GND and EN pins of the power switch to a slide/toggle switch. When the connection is made by the switch, USB power will be turned on.

If you're unsure of which version to order you probably want Logic Level which can be controlled using either a switch or regular GPIO output.

The USB3 Power Switch can be used to control power for many different types of USB3 device such as Flash drives, Webcams, etc.

Please Note:

• If your USB device/power supply negotiates a VBUS voltage higher than 5V when using Open Drain setting or changing the PU solder jumper to pull EN high it will be pulled to VBUS (the USB Power Switch itself can switch 5-20V).
• USB data lines are connected at all times.
• When "PU" solder jumper bridged away from PCB edge, "OD" solder jumper bridged away from PCB edge. EN pin is pulled high to VBUS. USB Power switch is normally ON but still controlled by high(on)/low(off) logic level on EN pin.
• When "PU" solder jumper bridged away from PCB edge, "OD" solder jumper bridged closest to PCB edge - Invalid - USB Power Switch is always ON.
