Usb hub
About the Usb hub PCB
Usb hub is an open source PCB design by chinh4, published on GitHub. It is a 2-layer board measuring 22.4 × 20 mm, with 20 components from 10 distinct parts.
Other key parts include the CY7C65634-28LTXC. By type, the board carries 10 capacitors, 7 resistors, 1 IC, 1 crystal and 1 connector.
It belongs with the usb & debug tools and keyboards designs in this gallery.
From the project
An ergonomic framework mod.
This adds an additional usb interface for the keyboard by using a usb hub controller using the pins from the fingerprint sensor connector on the touchpad, this is because I don't want to deal with the EC to make the keyboard work and just want something like qmk to run off the keyboard.
