FTDI USB 4-port TTL serial adapter

This FTDI adapter provides four TTL serial ports operating at 5 V and 3.3 V signal levels. It connects to a host via USB and presents each port as a separate virtual COM port. The integrated 5-port USB hub allows additional peripherals to share the same host connection. Developers and engineers use it for debugging, firmware flashing and multi-device serial communication.

3.3 V logic headroom and port limits

The 3.3 V TTL levels suit modern microcontrollers and logic analysers without external level shifting. Four simultaneous serial channels handle typical multi-UART test rigs, but the single upstream USB link caps aggregate throughput. Builds that need more than four independent serial streams or galvanic isolation will require additional adapters.

Questions about this item

Will this cable work with the 3.3 V serial ports on my older FTDI adapter?

Yes, the cable is rated for 3.3 V operation and matches the voltage level of the FTDI adapter's TTL serial ports.

How can I verify the cable is functioning correctly after connecting it?

Connect the cable to the adapter and check that each of the four serial ports enumerates in your operating system's device manager.
