Very nice piece of hardware

I like it very much, I cut some parts from official example and add some more.
I use it almost daily, there need some more done for power efficiency, but is good enough with how it is now around 16 hours at 10Mhz STBY speed.
In future an OLED version and IR receiver beside the IR TX will be welcome, for IR RX can be used the same photo-diode used for TX wired with a capacitor to an analog capable pin, good for fast remote cloning being possible to create FFT filtering to isolate the RX frequency carrier :) and USBC for the next version will be welcomed.
I haven't used the LoRa yet but I plan to use it very soon.
BTW if someone want a C++ lvgl wrapper written by me, here it is: https://github.com/dev-board-tech/lvglCpp , is in development but is functional :)

Great device for many purposes

Awesome little thingy to play around with the microcontroller and a lot of peripherals, I especially love the fact that you can remove the battery.
Well, of course also that you can flash it and program it however you like, 10/10

good watch

I do wish there was a little more information on the code for it but it isn't really information about the watch I am after so much as information on signals I'd like to replicate with it.

Great Dev kit.

Works great as a Dev kit. Not really fit as a daily use watch. There are a lot of glitches and crashes during the day. Also, Meshtastic firmware is not ready for use on this device due to power usage and crashes.

It works!

Don't forget to flick the switch under the battery to on! I was very frustrated with it not working for a few days and then during one of the trouble shootings with a multimeter I noticed the batter is doing fine and the switch is the only place that has power. flicking it to on made the watch start.

Note that this is not a smart watch meant for consumers. this is a smartwatch meant for creators and tinkerers. Don't expect it to be perfect user experience, expect it to be a perfect development platform and with that mindset, looks like they have delivered.
