The Adafruit CH334F Mini 4-Port USB Hub Breakout features a CH334F USB 2.1 hub chip, which converts one high-speed port into four.

Sometimes you've got something with USB host, like a embedded linux board, and you want to connect more than one thing. Or maybe you want to turn something like a keyboard into a multi-device USB peripheral. The Adafruit CH334F Mini 4-Port USB Hub Breakout will do that for you!

Most folks who use a USB hub get one that comes in an enclosure with connectors or cables included. But, those hubs are going to be bulky - they're meant for external use. This breakout board is designed to be compact, so it can easily be embedded into an enclosure or existing device. There's four mounting holes but other than that, Adafruit tried to keep it as compact as possible.

Part of how it's kept small is not including downstream ports! The breakout has either 0.1" header or USB C for the upstream, and then four 4-pin ports for peripheral connections. It's expected that folks to solder directly to the pads or use Adafruit's 'simple' USB-breakout cables.

You get one fully assembled/tested board and some header for if you want to plug it into a breadboard. Other than that, keep in mind there are no USB ports for the 4 downstreams - if you need those take a look at our micro B or USB-A hubs.

We also carry a 2-port version here which is a little more than half the size.
