Description
Description
Normally you'd just buy KVM switch (keyboard-video-mouse) for that purpose from the shelf, but I've decided to build one myself. Few reasons why:
- I don't need display switch, most of the displays have multiple inputs and able to switch automatically. Therefore I need KM-switch really.
- Of-the-shelf switches are quite expensive, as it turns out.
- I want to have USB hub built int, that is rarely the case for of-the-shelf units.
- Designing device for yourself is fun I want to do that
In this project I'm using
- TS3USB30E USB switch
- NE555 button controlled bi-stable vibrator
- TPS2115APW power manager
- FE1.1S USB hub
- USBLC6 for ESD protection
