The BoltGATE 20-25 is a Multi-service IoT Edge Gateway, EN50155 certified, and designed to exceed the requirements of rolling stock in the TX temperature class. With IP66 rating, it is extremely rugged and suitable for any application where consistent performance and reliability are a must.

Based on the Intel Atom E3800 processor family, with up to 4GB of RAM and 8GB of eMMC, the BoltGATE 20-25 offers extra storage expansions through optional internal or removable 2.5” SATA SSD/HDD, mSATA, and a user-accessible microSD slot.

At 30W max, the BoltGATE 20-25 is a fanless, compact unit that provides a large number of communication and I/O interfaces: two Gbit Ethernet, protected USB 2.0, four isolated serial interfaces, eight isolated DI/O plus odometer and key signals, CAN bus, video, and optional MVB. It also features a wide range of connectivity capabilities including one cellular modem, Wi-Fi, Bluetooth Low Energy, and a dedicated internal GNSS with Untethered Dead Reckoning.

As a result of its modular design, the BoltGATE 20-25 can easily be customized for the requirements of the target application. With three full miniPCIe slots, it can accommodate additional connectivity or communication options and, through Eurotech Professional Services, it can offer custom front panel configuration and connectors or customized software images.

The BoltGATE 20-25 comes with Linux and Windows operating systems. It offers Everyware Software Framework (ESF), a commercial, enterprise-ready edition of Eclipse Kura, the open source Java/OSGi middleware for IoT EdgeGateways. Distributed and supported by Eurotech, ESF supports ready-to-use field protocols (including Modbus, OPC-UA, S7), MQTT connectivity, web-based visual data flow programming and deep configuration. ESF is also integrated with Everyware Cloud (EC), Eurotech's IoT Edge Management Platform (separately available), enabling advanced diagnostics, provisioning, and full remote device access and management.

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