Description
Sometimes, you have a USB host like an embedded Linux board and want to connect multiple devices. The Adafruit CH334F Mini 2-Port USB Hub Breakout is a compact USB hub perfect for embedding into enclosures or existing devices.
Featuring a CH334F USB 2.1 hub chip, it converts one high-speed port into two. Unlike typical USB hubs, this breakout provides 0.1″ header or USB-C for upstream and four 4-pin ports for peripherals, allowing a very compact design without bulky downstream ports.
This product comes fully assembled and tested, with header pins included for breadboard use.
