Its of format of original ESP8 so you get serial + 3 IO pins
They are 4x the size though, almost exactly double in both length and width.
And this PCBA will be smaller than the battery in most applications anyway.
I love this. Fun and insightful article. Thank you.
Other than that, hugely impressive project of course, it makes any board I've tried to design/assemble look impossibly huge. :)
FTA:
> In a clear line of sight test with the f32 placed about 3ft off the ground I was able to connect and perform scans/control the LED at roughly 120ft!
Fun fact, at that size the whole f32 is smaller than the wavelength of the radio waves it's using for 2.4GHz WiFi. Not that this is unique by any stretch, but it's still fun to think about. (Edit: formatting)
Seriously? For a tiny board like this also? Genuine question.

It looks doable, but of course a lot of carefulling is required when placing the components.
Edit: Nevermind, I was wrong. I see now that the sizes don't actually directly correspond to the number codes! 01005 is 0.4mm x 0.2mm and 0402 is 1mm x 0.5mm. That's annoyingly confusing, IMO.
inch 0402, 0201, 01005, 009005, 008004, $1
mm 1005, 0603, 0402, 03015, 0201, 01005
I’m tempted to try a few of these just to see how disastrous my build efforts are.
Very nice.
The Sense versions are pretty rad. Now I only have to add a battery and a touch sensor and I'm good to go.
Question about the instructions in your README, you say that once you're done with the top side, repeat for the bottom, but when you're working on the bottom side, what stops the elements on the top side from falling off once the heat passes through the board and melts the solder on that side?
Basically you're hoping the bottom side doesn't get hot enough for everything to move or fall off.
