Ultra-Low-Power Processors

Discussions center on the power consumption of an ultra-low-power processor and its potential for battery-powered IoT devices, sensors, wearables, and remote applications, with comparisons to solar cells, ESP8266, and coin cells.

Would be interesting for powering IoT devices.

Show me applications in microwatt range to justify the "usable", moreover you need a wifi. Why someone should use that instead of a solar cell, like the one on calculators ?

Could it be used to power wireless mice, keyboards, etc? Things that are generally low power but still require batteries every N months?

It's a joke, but these processors are extremely low power. A coin cell can power them for years (depending on what it's doing)

In case you ever run it from the battery, how is the power consumption?

actinium226 Jul 1, 2024 View on HN

It seems to use 1ma when on, so if you hooked this up to one of the larger smartphone batteries at 5000 mah, this could run for 200 days.I'm not sure what you'd do with that, but I think as power consumption drops to 0 on these sorts of thing it might make some remote sensing applications cheaper/easier to deploy, if you could just deploy it with a battery and forget about it for a year or two.

What does power consumption look like? Is this useable for battery-powered applications?

matsemann Jan 6, 2025 View on HN

Is it also good for power for small devices? Can power down for longer between sending.

huh, seems like you could realistically power a low end watch, though.

This could still be useful for battery constrained devices, right?
