Neousys IGT-21 ARM-based Box PC is an Fanless Industrial IoT(Internet of Things) Gateway for In-Vehicle Communication. Unlike System on Module (SoM) that’s commonly provided as a barebone component, IGT-21 is based on AM3352 from Texas Instrument’s Sitara AM335x family and will be shipped as a ready system pre-installed with Debian. The industrial nature of IGT-20 means it is in compliance with common industrial certifications such as CE/FCC, shock and vibration. Another distinction IGT-20 has over SoM is that it accepts a wider range of power inputs ranging from 8 to 25 VDC (SoM usually accepts 5 VDC).

As an In-Vehicle Communication Industrial IoT Gateway, IGT-21 has I/Os that are applicable to a range of industrial grade sensors. It features one USB2.0, one 10/100M LAN, two configurable COM ports (RS-232/422/485) and an optional CAN bus port. In addition to the ports mentioned, there are 4 built-in isolated digital input channels that accept discrete signals from various sensors or buttons/ switches. There are also four built-in isolated digital output channels to control actuators and indicators.

Communication wise, IGT-21 has a mini PCIe slot and a USIM holder allowing it to transmit acquired data and system status in vehicle to vehicle communication (V2V) via 3G, 4G or WiFi (mini PCIe WiFi module). There is an opening on top of IGT-21 for users to mount the SMA connector of the wireless module. In terms of storage, IGT-21 has dual microSDHC slots, one internal and one external. This design allows users to separate system/ user data and can expedite in OS deployment for mass production. As a gateway, users can take advantage of six programmable status LED indicators and two control buttons to operate IGT-21 without using a keyboard/ mouse.
