    Best watch ever

    Hi Team Lilygo,
    This watch is incredible, I showed this watch to my audience via social platform and a lot of interaction wven on it’s unboxing video I got 10k+ views 😍.
    I am making series on it and complete it soon

    Everything I love about ESP32/Arduino, but better

    I love boards such as Arduino thanks to the amazing creative potential. With the right amount of skill and interest (and time), one can create pretty much anything. The T-Watch 2020 (v3) I just received goes even beyond. It's tidy, lightweight and completely codeable. Also it has an amazing set of capabilities, thanks to the great selection of hardware components. It's only been a day since I received my watch and I already spent hours and hours exploring the library and creating a very specific watch for my needs - and some more time creating games and IR control apps for my home appliances. It's amazing, simply amazing. If you like the freedom of customizing and learning, this product is an excellent option.

    Wow, it sounds like you've made yourself a satisfying watch, congratulations. Thank you for your sharing.
    Looking forward to hearing more about your voice.
