Thread: Use Serial1, Serial2, etc with CP2104?

    Use Serial1, Serial2, etc with CP2104?

    I have a CP2104 "Friend" board from AdaFruit and I want to use it to send serial output to USB on Linux. I can just connect the RX/TX pins of the Serial1 (as an example) to the RXD/TXD of the CP2104, and it will handle the rest? There are two other pins, DTS and CTS. Are these required to be connected? The other two are 5v and GND, so I think I have those handled. :-)

    Normally you need 3 wires, RX1->TXD, TX1->RXD, and GND-GND.
