Forecr RAIBOARD-ORNX-NANO4 NVIDIA Jetson Orin Nano 4GB Railway-Grade Carrier Board with Isolated CAN, Dual GbE and Wide Temperature

A railway gateway that mainly moves data between the vehicle bus, serial devices and a cellular link needs very little AI compute, but it still needs railway-grade I/O. The RAIBOARD-ORNX-NANO4 fits the NVIDIA Jetson Orin Nano 4GB to the Forecr RAIBOARD-ORNX railway-grade carrier board, supplied with the module fitted.

The Orin Nano 4GB module delivers 20 TOPS from a 512-core NVIDIA Ampere GPU with 16 Tensor Cores and a six-core Arm Cortex-A78AE CPU, with 4 GB of memory, and Forecr lists support for the module’s Super mode. For a different balance of compute and cost, the RAIBOARD-ORNX-NANO8 and the RAIBOARD-ORNX-NX16 carry the other modules on the same board.

On the RAIBOARD-ORNX-NANO4, field interfaces are isolated and sit on locking Molex Dura-Clik connectors: two CAN bus ports, two RS-232/422/485 ports, four digital inputs and four digital outputs, beside two Gigabit Ethernet ports. An HDMI 2.0 output on a sealed Amphenol connector, a USB 3.0 Type-A port and a USB 3.0 Type-C recovery port cover local access. Two M.2 Key-M slots take SSDs, an M.2 Key-B socket with nano-SIM takes LTE or 5G and an M.2 Key-E takes Wi-Fi. A 120-pin Samtec connector carries four 2-lane CSI ports; Forecr lists up to four GMSL2 cameras through an add-on board.

Power is 10-75 V DC on a four-pin Molex Micro-Fit connector, with a draw Forecr gives as under 60 W, and the board is rated from -25 to +85 °C. It is the board inside Forecr’s RAIBOX-ORNX computers, which Forecr designs to meet EN 50155 and IP67 with that enclosure. Forecr lists Ubuntu 20.04 and 22.04 with JetPack 5.x and 6.x. The RAIBOARD-ORNX-NANO4 suits onboard rail, trackside and gateway designs where the board is mainly a gateway.
