Overview

The Robustel R1511P-4L Embedded LTE Router Serial is a fully featured embedded 4G router targeted at applications such as EV Charging, traffic signs, vending machines, medical instrumentation, industrial instrumentation and many more IoT-type applications. An embedded router solves two problems that traditional routers do not – cost and size.

The Robustel R1511P-4L Embedded LTE Router Serial is a cost-effective small-footprint board with Ethernet WAN, Wi-Fi WAN and 4G WAN interfaces that can all be independently configured in the powerful onboard Operating System. RobustOS.

RobustOS is Robustel’s brilliant Linux-based router operating system that offers functionality that could take a software engineer many months to write and even more months to adequately test. Key features of RobustOS include:

RobustVPN – innovative use of Open VPN tunnelling to provide a fixed IP address on the router anywhere

RCMS – Robustel’s Cloud management platform – essential for managing an estate of routers – can be OEM branded

SMS Control – total control of the router using SMS for general status or fixing fault conditions with IP Comms

Automated failover – configure the router to automatically fail from WAN/Wifi to 4G with just a few clicks

KeyFeatures

  • Small footprint powerful 4G router board – fully customisable in software
  • Dual Ethernet, Wifi (AP and client) and 4G/3G/2G capability
  • RS232 (default) or RS485 port for connection to serial devices + integrated Modbus gateway
  • Pre-certified PCBs minimize manufacturer certification challenges.
  • Fully programmable Linux environment with excellent SDK Documentation
  • Connect the R1511P Embedded 4G/LTE Router directly to a Raspberry Pi or similar low-cost embedded PC for internet access.
  • Bulk packaging + shipping options to minimise addition to customer BOM cost
