Hi,
For a measurement equipment, I need to convert 4 serial interfaces (TTL) to one USB output on a PCB.
The serial conversion to USB is easy with Prolific or Silabs chips - but only single.
So I thought to use an USB Hub to join the 4 serial2USB modules.
But I did not find an easy to use USB Hub solution.
I know you can buy an external USB Hub for 5$ in the supermarket, but I need it designed on a PCB.
Does anybody has designed an USB Hub onboard already?
Which chip can preferrably be used?
