About the Usbuh PCB
Usbuh is an open source PCB design by jphwba, published on GitHub. It is a 2-layer board measuring 90 × 55 mm, with 65 components from 24 distinct parts.
Other key parts include the FE1.1s, GL823K, AMS1117-3.3 and PCM2902. By type, the board carries 26 capacitors, 19 resistors, 5 ICs, 5 fuses and 3 crystals.
From the project
This is a USB Hub that features USB-C input, an Auxilary Port with Audio in and out, three USB-A 2.0 ports, two USB-C 2.0 ports and a micro SD Card slot. The main USB hub controllers are two FE1.1s's, a GL823K for the micro-sd controller, an AMS1117-3.3 to step down 5v connection
This is a USB Hub that features USB-C input, an Auxilary Port with Audio in and out, three USB-A 2.0 ports, two USB-C 2.0 ports and a micro SD Card slot. The main USB hub controllers are two FE1.1s's, a GL823K for the micro-sd controller, an AMS1117-3.3 to step down 5v connections into 3v3 and a PCM2902E for the audio controller. I made this because on my desk the area where my PC is requires the top IO to be blocked which had all of these ports and there was no space to run a cable it was a very tight gap so my current solution is running a $5 temu adapter which goes through a USB-C to USB-A…
