## Description

The Adafruit CH334F Mini 4-Port USB Hub Breakout converts one USB host port into four 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 four 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 compact as possible. Key Features CH334F USB 2.1 Hub – Converts 1 upstream port to 4 downstream ports Compact Design – Optimised for embedding in enclosures and devices Upstream Options – USB-C connector or 0.1" header pins Downstream Pads – 4× 4-pin solder pads for direct wiring 4 Mounting Holes – For secure installation High-Speed USB – Full USB 2.1 hub functionality Also Available CH334F Mini 2-Port USB Hub Breakout – Same design with 2 downstream ports in a smaller footprint Ideal For Embedded Linux boards needing multiple USB devices Converting single-USB peripherals into multi-device hubs Custom enclosures and device modifications Compact projects where standard USB hubs are too large Note: No USB connectors are included for the downstream ports.
