• what about GND, is it connected too?

  • GND is connected to GND...

    I'm using this https://www.amazon.com/gp/product/B07XF2­SLQ1.

    TTL's pins are: DTR, RX, TX, VSS, CTS, GND

    Puck -> FT232R connections are:
    V3 -> VCC (set at V3.3 and not V5)
    GND -> GND
    D28 -> RX
    D29 -> TX

    (edit: changed pin TS to CTS -- misread it)
