Not compatibility

Really hard to setup the envirionment to code watch with c++ arduino ide, and there is not any working library for micropython.

lack of documentation

The product is very good but there´s poor documentation, for example how to make your own usb connected sensor. You can run out of the box some examples but further is really a challenge, that would be less painful if some written docs are well mantained.

First impressions of the T-Watch 2020 V3

I am using this watch as a display for my Electric conversion of a 5hp 4 st outboard motor, quite pleased with the ergonomics of the watch, not so impressed with the programming, took quite a while to find a suitable base program to use. A lot of examples on Arduino but they all needed work to work properly, The battery life is a bit short but probably ok for my use, very concerned about the charge current at 500mA on a 350mAh battery I think this will mean a replacement will be needed sooner rather than later.
Overall pleased with the watch so far. Looks a lot better in real life than the picture, shows the three bar graph screen, there are several other screen you can scroll to for other metrics.
