Neousys IGT-21 is an ARM-based fanless in-vehicle communication IoT and IIoT gateway (Internet of Things). In contrast to System on Module (SoM), which is usually provided as a barebone component, IGT-21 is based on AM3352 from the Sitara AM335x family from Texas Instrument and is delivered as a finished system with pre-installed Debian. The industrial nature of IGT-20 means that the usual industrial certifications such as CE / FCC, shock and vibration are met. Another difference IGT-20 differs from SoM is that it accepts a wider range of power supply inputs between 8 and 25 VDC (SoM usually accepts 5 VDC).

As an in-vehicle communication IoT gateway, the IGT-21 has I / Os that can be used for a range of industrial-quality sensors. It has a USB2.0, a 10 / 100M-LAN, two configurable COM ports (RS-232/422/485) and an optional CAN bus port. In addition to the connections mentioned, there are 4 integrated isolated digital input channels that accept discrete signals from various sensors or buttons / switches. There are also four integrated isolated digital output channels for controlling actuators and displays.

In terms of communication, the IGT-21 has a mini PCIe slot and a USIM bracket, with which it can record data and the system status in the vehicle via 3G, 4G or WiFi (mini PCIe WiFi module) to the Vehicle communication (V2V) transmits. There is an opening on the IGT-21 in which users can attach the SMA connector of the radio module. In terms of storage capacity, the IGT-21 has two microSDHC slots, one internal and one external. This design enables users to separate system / user data and accelerate the deployment of the operating system for mass production. As a gateway, users can use six programmable status LED indicators and two control buttons to operate IGT-21 without a keyboard / mouse.
