A 1-metre USB-C extension cable with an inline power switch that maintains full USB 2.0 data connectivity. Unlike typical USB power switch cables that only toggle VBUS, this cable also connects the D+/D- data lines, both Configuration Channel pins (CC1 and CC2), and the shield — giving you complete control without sacrificing data transfer.
Perfect for development workflows where you need to power-cycle a connected board without unplugging it. Whether you're debugging a Thing Plus, testing battery life without USB charging, or using Power-over-Ethernet while keeping a USB data link, this cable makes it simple.
Key Features
- Inline Power Switch – Toggle VBUS power on and off without disconnecting the cable
- Full USB 2.0 Data – D+/D- data lines connected through, unlike power-only switch cables
- CC1 & CC2 Connected – Both USB-C Configuration Channel pins pass through for proper USB-C negotiation
- Shielded – Shield connection maintained for signal integrity
- TPE Sleeve – Soft, durable cable jacket built to last
- 1m Length – Generous cable length for bench setups
Ideal For
- Power-cycling development boards without unplugging
- Battery life testing — keep USB data while disabling USB power
- Power-over-Ethernet (PoE) setups that need USB data without USB power
- Any project requiring independent control of USB power and data
Package Contents
- 1× USB-C Extension Cable with Power Switch (1m)
Jargon buster
Plain-language definitions for the technical terms used above.
- PoE
- Power over Ethernet lets one Ethernet cable carry both network data and electrical power. This is useful when installing a device where running a separate power adaptor would be difficult.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- Thing Plus
- Thing Plus is SparkFun’s development-board form factor with a small rectangular layout and connections suited to wireless and battery-powered projects. It matters because boards and accessories in the same form factor are easier to mount, wire, and swap between projects.
- USB 2.0
- USB 2.0 is a wired connection standard used for data and power between a device and a computer or compatible host. For this camera, it tells you what kind of port it plugs into and helps indicate whether older or newer computers are likely to work with it.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
- VBUS
- A label often used for the main bus or supply voltage being measured or distributed on a board. Knowing what VBUS refers to helps you wire the monitor to the correct point in the circuit, especially for high-side measurements.
