Forecr DSBOX-ORNX-AC4 NVIDIA Jetson Orin Nano 4GB Fanless Embedded Computer

A single camera, one compact model and a site with no air conditioning describe plenty of real edge AI jobs, and for those the priority is a unit that survives the installation rather than the largest module. The DSBOX-ORNX-AC4 is the entry fanless embedded computer in the Forecr DSBOX-ORNX series, built around the NVIDIA Jetson Orin Nano 4GB.

The Jetson Orin Nano 4GB pairs an NVIDIA Ampere GPU with Arm64 CPU cores and 4 GB of 64-bit LPDDR5, enough for single-stream detection, classification and counting tasks. The DSBOX-ORNX-AC4 supports Ubuntu Linux 20.04 with JetPack 5.1, the same software base as the larger modules in the range, so an application can move up a tier later without a rewrite.

Choosing the entry module does not reduce the connectivity. The DSBOX-ORNX-AC4 provides one Gigabit Ethernet port, two USB 3.1 Type-A ports, an HDMI 2.0 output at up to 3840 x 2160, one CAN bus port, one RS232 and one RS422 port, and two digital inputs with two digital outputs, along with a micro USB 2.0 recovery port. Two M.2 Key-M slots take SSD storage, one 2280 socket on four PCIe lanes and one 2230 socket, while an M.2 Key-B socket with SIM slot and an M.2 Key-E socket add LTE, 5G or WiFi modules, which lets an unattended unit report over cellular. Power comes from a 9-28 VDC input.

Forecr builds it for industrial sites, with thermal management that cools the module without a fan across a -25°C to +85°C ambient range. At 110 x 130 x 60 mm and 760 g, the embedded computer fits small enclosures and machine frames. Where the workload needs more memory, the DSBOX-ORNX-AC8 carries the Orin Nano 8GB, and the DSBOX-ORNX-AB16 moves to the Jetson Orin NX 16GB.
