OIKWAN USB to RS232 Adapter with FTDI Chipset
Bottom line: The OIKWAN USB to RS232 Adapter with FTDI Chipset ($9.99 on Amazon as of 2026-10-06): Genuine FTDI FT232RL chip, not a cloned bridge that breaks on driver updates; main trade-off: male DB9 only, so female-port devices need a separate gender changer.
