Content 4/4

This is 4 port USB to UART converter with chip FT232RL with USB hub FE1.1S. Logic level for FT232RL is 1.8V, 3.3V and 5V. Board have 4 separate jumper, for disable any UART channge. Using jumper is possible disconnect power supply for any channel.


It's a great extension to remove a lot of cabling from the table. All you need is one PCB, and you have 4 USB to UART converters on the table.




Schematic, PCB designe and more is on the my github repository.
