Or maybe you want to turn something like a keyboard into a multi-device USB peripheral. The Adafruit CH334F Mini 2-Port USB Hub Breakout will do that for you! It features a CH334F USB 2.1 hub chip, which converts one high-speed port into two.\u003c\/p\u003e \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, we tried to keep it as compact as possible.\u003c\/p\u003e \u003cp\u003ePart of how we kept it small is not including downstream ports! The breakout has either a 0.1\" header or \u003ca href=\"\/hi\/products\/usb-a-to-usb-c-cable-1m\"\u003eUSB C\u003c\/a\u003e for the upstream and four 4-pin ports for peripheral connections.
