Or maybe you want to turn something like a keyboard into a multi-device USB peripheral. The \u003cstrong\u003eAdafruit CH334F Mini 2-Port USB Hub Breakout\u003c\/strong\u003e will do that for you!\u003c\/p\u003e\n\u003cp\u003eMost 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 and easily embedded into an enclosure or existing device. There are four mounting holes but other than that, it's as compact as possible.\u003c\/p\u003e\n\u003cp\u003ePart of how Adafruit kept it small is \u003cem\u003enot\u003c\/em\u003e including downstream ports!
