Here's the comparison of the two HZHY-AI Compact systems on cooling, power input, and USB ports:
| Attribute | HZHY-AI528Compact | HZHY-AI629Compact |
|---|---|---|
| Cooling | Fan | Fan |
| Power input | 12–36 V | 24–36 V |
| USB ports | 2 | 1 |

Key differences:
- Power input: The AI528Compact accepts a wider range (12–36 V), which gives you more flexibility with 12 V supplies; the AI629Compact starts at 24 V.
- USB ports: The AI528Compact offers 2 USB ports vs 1 on the AI629Compact.
Both are fan-cooled, and both are Active-status Jetson-based full systems supporting Orin NX / Xavier NX modules with 100 INT8 TOPS (sparse, Base) AI performance and 1.88 TFLOPS FP32 (based on the module inside). If a wider power input range and the extra USB port matter for your deployment, the AI528Compact is the more flexible of the two.
