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
Package Contents
- 1× Adafruit CH334F Mini 4-Port USB Hub Breakout (assembled and tested)
- 1× Header strip
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- USB host
- A USB host is the side of a USB connection that controls attached devices, like a computer talking to a keyboard or flash drive. This matters because most microcontroller boards are normally USB devices, so adding USB host support lets them use common USB peripherals.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
