By offering integrated hardware and software connectivity towards the Field and the Cloud, the BoltGATE 20-25 MVB Edition is a Multi-service IoT Edge Gateway, EN50155 certified, designed to address the challenges of the next-generation applications for smart transportation and connected railway.  

Based on the quad core Intel® Atom™ E3845 processor, with 4GB of RAM and 8GB of eMMC, the BoltGATE 20-25 is a fanless, compact unit designed to exceed the requirements of rolling stock in the TX temperature class with an IP66 enclosure. It features a large number of I/O interfaces – protected USB 2.0, isolated serial interfaces and DI/O, and CAN bus interfaces – and a wide range of connectivity capabilities including two Gigabit Ethernet, one LTE CAT 4 cellular modem, Wi-Fi, Bluetooth Low Energy, and a dedicated GNSS with Untethered Dead Reckoning.

The MVB Edition of the BoltGATE 20-25 adds integrated hardware and software components to interface with the train bus through two MVB ports on DB9 connectors. MVB options include EMD and ESD+ interfaces, both available in Read/Transmit or Read Only configurations. A dedicated 32-bit MVB controller supporting all process data offloads the CPU and ensures accurate programmable sampling from 1024 down to 16 milliseconds for each individual port. Powered by the Eurotech IoT Edge Framework, Everyware Software Framework (ESF), the BoltGATE 20-25 MVB Edition has full software support for the MVB interface. The friendly ESF web-based user interface allows to visually compose powerful data flows to acquire data from the bus, analyze it on the Edge, and publish it to the Cloud though the popular MQTT protocol. Everyware Cloud, Eurotech IoT Integration Platform, completes this solution by providing data integration to the applications and by offering complete management of the devices deployed on the field.

For customers requiring more configuration flexibility, Eurotech Professional Services offer an extensive number of options, both for the hardware (e.g. additional features, custom front panel/connectors, branding) and for the software (e.g. customized application images). 

The BoltGATE 20-25 MVB Edition is AWS IoT Core Qualified and can be integrated with 3rd party cloud services.
