The BoltGPU 10-31 is a rugged subsystem that has been designed to deliver GPU acceleration to Rolling Stock and Automotive applications.

Based on NVIDIA Jetson Xavier NX, it combines a 6-core, high-performance ARM CPU with a 384-core GPU and 48 Tensor Cores, offering exceptional power efficiency and up to 21 TOPS of accelerated computing.

The BoltGPU 10-31 is a power efficient, stand-alone unit that enables traditional and GPU-accelerated workloads in harsh environments, and comes with Automotive and Rolling Stock certifications, such as EN50155, EN45545 and E-Mark.

With a very complete set of high-speed interfaces, the BoltGPU 10-31 can be used to process multiple video streams from high speed, high frame rate cameras: it provides 3x GbE, 4x GMSL and 3x USB3.1 Gen 2 ports (noise and surge protected) that can be used to connect sensors and to create sophisticated networking architectures. Wireless connectivity is also cutting edge, thanks to Wi-Fi 6, BT5.1 and support for optional LTE modems.

The BoltGPU 10-31 offers plenty of storage capacity for video and other data via an internal NVME unit; removable storage is also supported via a microSD interface.

On-vehicle features include isolated CAN-FD and opto-isolated DIO, a GNSS with Untethered Dead Reckoning (optionally RTK), and rugged M12 connectors.

Other transportation and heavy-duty enablers are a wide range power input (24-110VDC, EN50155) with ignition sense and EN50155 OT3 operating temperature range (-25 to +70°C).

The BoltGPU 10-31 shares the same form factor of the BoltGATE 20-31 and of its expansion modules, making it possible to create hybrid architectures with extra features.

For customers seeking a tailored product, Eurotech offers a range of personalization and full customization options, ranging from branding (“skins” and color) to deep HW/SW configurations.
