# REGULUS System-on-Module (SoM)

## Product Summary

![REGULUS System-on-Module (SoM)](/res/image/MLM-1_SoM_3.jpg)

**REGULUS** is a compact AI System-on-Chip (SoC) with **10 TOPS of computing power** at under **3W** of power, optimized for higher-performance on-device AI use cases in power- and space-constrained applications such as drones and security systems.

REGULUS comes pre-equipped on a system-on-module (SoM) board, making it a fully functioning AI PC in itself.

Programs for REGULUS are built in a cross-compilation environment and run on the module's ARM CPU. See [(Basic) Running Pre-Compiled ResNet50](tutorial_resnet50.md#for-regulus) for the cross-compilation workflow.

## Identifying the Hardware Revision

REGULUS ships in different hardware revisions — `regulus-ra` and `regulus-rb`. Run the following on the device to check its revision:

```bash
regulus-version 2>/dev/null | awk -F': *' '/^HW Revision/{print $2; found=1} END{if(!found) print "regulus-ra"}'
```

You can also identify the revision from the board silkscreen markings.
