[Q] Android Wear SmartWatch Hardware DIY topic

Hello everyone, i want to ask something about Android Wear OS and Hardware Specs which is related my Bachelor of Science Thesis subject. First of all, I searched the forum; there were no answers about my question, I also searched developer.android.com/wear and there were no extra information, it contains information about well-known smart watch developers' products such as sony, samsung, lg, etc...

so, my intention is building both software and hardware parts of a special version of android wear device. that means, i need to etch special pcbs, solder chips onto that pcbs, mount capacitive touchscreen, build metal body (cnc cutted) on hardware side

then i must reconfigure, rebuild and fine-tune the stock android wear rom for my specially built hardware, for example my design includes 9-DOF IMU sensor, then i must write its driver (*.so) for my hw, and so on...

And the question is, i want to know if there is any documentation or technical datasheets, example pcb designs, hardware compatiblity lists, reference diy projects, etc?

thanks guys
