Hugging Face Microduck 续航超 3 小时

AI 导读

Hugging Face 的 Microduck 换用定制主板后，在 2600 mAh 电池上自主运行超过 3 小时，此前 Radxa 原型机 20 分钟即因过热降频关机。测试中平均电池电流从约 1.13 A 降至约 0.82 A，约省电 28%；CPU 峰值温度从 114°C 降到 60°C，全程零热降频，这次是电池先耗尽。

We did not know how long Microduck would actually last on battery

We had thermal management issues with our Radxa prototypes: throttling after just 20 minutes, followed by an overheating shutdown.

We addressed this with the new custom board. To test it, we let Microduck roam autonomously in a dedicated area, walking around, standing and sitting until the battery ran out.

The results are way better than we hoped :)

- Over 3 hours on a 2600 mAh battery.

- Estimated average battery current dropped from ~1.13 A to ~0.82 A, roughly 28% less.

- Peak CPU temperature dropped from 114°C to 60°C, with zero thermal throttling throughout the test.

This time, the battery ran out before the cooling did :)

Very happy with the progress!
