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.
This USB hub adds the following additional features to those offered by the FE1.1s:
- Switches to on/off and reset individual USB ports.
- Capability to provide a maximum of 3A of current from each USB port.
- Power using 9V to 15V DC voltage source.
This USB hub uses a PIC16F630 MCU and four LM2596-5.0 switching regulators.
