hey Group,
this is not my project but I wanted to bring it to your attention...
https://www.crowdsupply.com/sqfmi/watchy
and here is the schematic

I wonder how it would do with our favorite Annex?
The campaign ends in 7 days (as of this writing)
I'm tempted to pick one up at $50

Your thoughts?

Hi Dwight,
It will probably work with Annex but it is so specific that there are many other devices that need to be supported (display, accelerometers, etc.).
At the same time, I found it to be very expensive compared to other products already available on aliexpress, like this one

hi ,
just bought a lilygo t-watch version 3.
st7789v lcd
bma 423 axis sensor
Max98357A i2s
motor on gpio 4
touch board
i2c mic
pmu axp202 ?
infrared on io13
after playing with some arduino examples i found the most samples are not working really.
the hardware test works fine and and shows the features.
at the end i installed Annex 32 !!!
it startet !!! and i can code in the editor !!!
a few seconds after starting the motor on gpio 4 starts to run and get verry hot.
setting pin 4 to 0 solve the problem.
make a buzzer motion :
Code: [Local Link Removed for Guests]
pin.mode 4,OUTPUT
pin(4) = 0
pause 400
for r = 1 to 20
pin(4) = 1
pause 11
pin(4) = 0
pause 51
next
its cool and maybe i found some features but not much time atm.
hope u like the info.
mfg
