Sky Star Extension Board

This extended version is mainly intended for users with many independent functional modules that require 5V or 3.3V power. The voltage is selected using the jumper cap on the right side of the lead-out pins. The screen can be fixed to the SkyStar board using double-sided foam tape, but the screen's FPC will block the memory card. You can reinstall the screen after installing the memory card (tweezers are required).
 
The board has a surface-mount 6050, a buzzer, and a screen driver circuit, allowing for small acceleration or gesture-based applications, such as a gravity-sensing game console or menu selection controlled by acceleration
. (I forgot to take pictures during installation, so here's a 3D image).

The screen does not block the three onboard buttons on the SkyStar board. Resetting and downloading do not require re-leading
 
the screen. The test program is not yet written. Except for the screen and 6050, other components are working normally. The 6050 seems to have a cold solder joint; I'll try resoldering it with a bare board after some time. Updates will follow after testing.
