2INTRODUCTION
Volansys presents you a smart modular customizable multi-service reference design of Gateway for
Internet of Things named as –“Modular Gateway”, targeted for multiple use cases in various segments
of IoT such as Smart Home, Buildings and Industries. Core features are its Modular Hardware Design and
Multi-Radio Connectivity (i.e. Wi-Fi, BLE, NFC, Thread and ZigBee).
This document is the hardware user guide for Modular Gateway. This manual provides detail
information about major design peripherals and its usage criteria. It also includes systems setup &
debugging information from hardware systems perspective.
2.1 Board Overview
Figure 1 - Modular Gateway
The Modular Gateway development kit, based on i.MX6UltraLite introduces developers to the i.MX6UL
based SOM board. This gateway will help users to develop and run their IoT based concept using
wireless interfaces like Wi-Fi, BLE, NFC, ZigBee and Thread. It supports Wi-Fi and Ethernet for connection
with cloud.
Modular Gateway supports various hardware module through MikroBUS Header such as Volansys’
KW2xD and KW41Z Thread and other Mikrobus standard supported modules. Also PN7120 base NFC
module and NXP JN5169 ZigBee Module.
