The Adafruit CH334F Mini 2-Port USB Hub Breakout converts one USB host port into two downstream ports using the CH334F USB 2.1 hub chip. Designed to be compact and embeddable, it fits inside enclosures or existing devices where a standard USB hub would be too bulky.

The upstream connection can use either the 0.1" header pins or the USB-C connector. The two downstream ports are broken out as 4-pin pads for direct soldering or cable connections — no bulky USB connectors are included, keeping the board as small as possible.
