I mean that is bluetooth radio, so its cheating just a little :)
No, I get your point. the ESP stuff I do spends most of its time in deepsleep, so yeah the 15ma is not great, but its not _that_ much of an issue because I can just wake up less often. Not having to use C is even better though.
10 year previous me would be screaming at my attitude. I remember when the pyboard came out and I was very much "pfftt, amateurs. 35mA to do nothing very fast"
However having lots of connectivity really makes up for the not great consumption. I don't have to slap on an RF solution, or like I did 12 years ago, use a horrific ethernet->rs232 bridge.
However if I need online low power consumption, I'll need to use STM32, and cry at how bad the documentation is(or was, I've not tried to use it for years).
- dragontamer 4y agoThe Cortex M23 and Cortex M33 chips seem to be the lowest power I can find. That's Microchip's SAM L10/L11, STM32U5, and the Nordic Semiconductor chip I mentioned earlier. Probably a few more out there (ARM sells their core to many different companies after all).
