ELIATER 2-Port PCIe Serial Expansion Card with Industrial DB9 RS232 COM Ports

Bottom line: The 2-Port PCIe Serial Expansion Card with Industrial DB9 RS232 COM Ports ($21.98 on Amazon as of 2026-10-06): Two DB9 RS232 ports on one x1 PCIe slot, no legacy motherboard header needed; main trade-off: drivers ship on a CD (CH38XDRV) - you need an optical drive or a separate download.

Pros & Cons

Pros

  • ✓ Two DB9 RS232 ports on one x1 PCIe slot, no legacy motherboard header needed
  • ✓ 16C550 UARTs push up to 230400 bps for fast serial logging
  • ✓ WCH382 chipset ships signed drivers for XP through Windows 11, 32 and 64-bit
  • ✓ Low-profile bracket included, so it drops into SFF and 2U chassis
  • ✓ Plug and play auto-assigns IRQ and IO address, and supports IRQ sharing

Cons

  • ✗ Drivers ship on a CD (CH38XDRV) - you need an optical drive or a separate download
  • ✗ Listing text contradicts itself on speed: 230400 bps in features, 115200 bps in the description
  • ✗ No DB25 or parallel port, despite the packaging note mentioning a parallel item
  • ✗ ExpressCard/34mm compliance claim is odd for a desktop PCIe card - verify fit before buying
