The main difference is cooling. The ALP681 has no fan, works in colder conditions (down to -25 °C) and weighs much less. The ALP681F has a fan, works in hotter conditions (up to 70 °C, but only with airflow) and is more than twice as heavy. Both are Leetop Edge AI Box PCs built on Jetson AGX Orin.

| ALP681 | ALP681F | |
|---|---|---|
| Cooling | No fan (passive) | Fan (active) |
| Operating temperature | -25 °C to 65 °C | -20 °C to 70 °C (needs airflow) |
| Weight | 1065.95 g | 2800 g |
| Dimensions (L × W × H) | 166 × 221 × 62 mm | 175 × 224 × 65.4 mm |
What this means for you:
- Choose the ALP681 if you need a silent, fanless unit, or if it will run in colder places down to -25 °C. It also weighs much less (about 1.07 kg vs. 2.8 kg).
- Choose the ALP681F if it will run in hotter places up to 70 °C. The full -20 °C to 70 °C range only holds when the unit gets airflow. leetopgrou...leetopgroup.com ↗“thermal.operating_temp_condition=Requires airflow”
The two models share most other specs: 275 TOPS of AI performance, 64 GB memory, 5 USB ports, and 1GbE + 10GbE Ethernet. One other difference: the ALP681F has two GMSL camera inputs and the ALP681 has one. leetopgrou... +1leetopgroup.com ↗“io.gmsl_camera_inputs=1”leetopgroup.com ↗“io.gmsl_camera_inputs=2”
