Spot on. I was so excited to see the form factor, and then my excitement was deflated as soon as I noticed the component details.

Note to any hardware hackers out there: I would buy the crap out of a unit in this form factor with an ESP32, LiPo charging, and proper deep-sleep oriented circuit design (I have seen too many circuits with cheap voltage regulators leaking many tens of μA).

You may be interested in our other product Franky then :)

That page just has some pictures. Is there a GH repo for the design, or some other kind of documentation? I would love to learn how this is built.

this is more promising but you forgot the keyboard

can you plug in an external keyboard

or are you supposed to program it via whisper.cpp speech recognition

Doesn’t look like it’s available to purchase though :(

I can see the beepberry page but this gives a generic database error.

I had the same result. This is the best photo/description I could find: https://www.hackster.io/news/sqfmi-s-franky-gets-a-blackberr... .

javascript developers be like, tens of microamps? i've forgotten how to count that low. i don't even get out of bed for less than two peer amps

but i just want to wake up for five milliseconds

And the ESP32 (Xtensa ones anyway) have pretty meh deep sleep as well. It’s the entire reason we have it power gated and use an STM32G0 (and now an L4) on our board at work :(

how low power have you been able to get the esp32 to sleep, if you don't mind sharing? and the stm32g? i'm sure the l4 is fantastic

wrt xtensa, in theory risc-v ought to help them with lowering the power suck (it sure helped the gd32v) but i'm not sure it makes a difference in sleep

and of course for milliamps per mips, going to subthreshold switching like ambiq will make a much bigger difference than anything architectural
