Introduction


Expand legacy-free industrial PCs, edge computers or digital-signage players into reliable serial networks with the Neuftech IIO-COMB Series. The card plugs into any M.2 2230 A- or E-Key slot that exposes PCIe ×1 and instantly provides two software-selectable RS-232 or RS-485 ports. Engineered for 24-hour factories, outdoor cabinets and in-vehicle gateways, every unit operates from –40 °C to +85 °C, survives ±15 kV ESD and delivers 2.5 kV isolation on the RS-485 variant. A 30 cm, EMI-shielded flat cable terminates in standard DB9 males, so you can mount the ports on a blank PCIe bracket or panel cut-out. Drivers for Windows 10/11 and Linux (3.8+) are WHQL & Ubuntu LTS certified, eliminating compatibility guess-work. Whether you need long-range multi-drop RS-485 for Modbus sensors or hardware-handshaked RS-232 for legacy CNC machines, the IIO-COMB gives you industrial durability in the world’s smallest form factor


Features


  1. [Wide-Temperature Reliability] Works from –40 °C to +85 °C for uninterrupted serial communication in outdoor kiosks, factory floors and edge AI boxes.
  2. [Dual-Protocol Flexibility] Choose 2×RS-232 (256 kbps, 3.3 V) or 2×RS-485 (500 kbps, 5 V, half/full-duplex) on one M.2 card—no extra adapters needed.
  3. [Industrial-Grade Protection] ±15 kV ESD, 2.5 kV isolation on RS-485 version, and solid-state capacitors give 24×7 immunity to noise and surges.
  4. [Driver-Free Setup] Windows 10/11 & Linux kernels 3.8+ detect the AX99100 chipset instantly; WHQL & Ubuntu LTS certified—no hunting for CDs.
  5. [Space-Saving 2230 Form] Fits any M.2 A or E-Key socket with PCIe ×1 signal; 30 cm flat cable routes DB9 ports to bulkheads without blocking airflow.
