4-Port High Power USB 2.0 Hub

4 Port high power USB hub =========================

This project is about a high current USB 2.0 hub that is specifically designed to drive USB powered development boards and experimental peripherals.

The core element of this USB hub is the FE1.1s USB 2.0 hub controller. The FE1.1s is a low cost, 4-port, high-speed USB hub controller you should be able to find on eBay or AliExpress.

Usb2-power hub: common questions

What microcontroller does the Usb2-power hub use?

The Usb2-power hub is built around the PIC16F630, from the PIC family.

How big is the Usb2-power hub PCB?

The Usb2-power hub measures 103.3 × 63.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb2-power hub?

96 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb2-power hub design files?

From the dilshan/usb2-power-hub repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Usb2-power hub design in my own project?

Yes, under the terms of its MIT license, which dilshan chose for the repository.

Can I test firmware for the Usb2-power hub without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
