关于LCD Shield的意见
The shield works so far and it is a nice product in principle.But there are some strange decisions in board design:
- Positioning of the RST-button right in the neighborhood of the other buttons is not a good idea.（把Reset 按钮放在其它按钮旁会很奇怪）
- I had to solder some more pins on the board by myself to access the 3.3 V. （我需要焊一些针脚才能用3.3V）
- Some pins are not connected to anything （一些引脚没有用）
- A strange mix of male/female pins （非常奇怪的公母引脚组合）
- It would have been nice to print the pin numbers etc. on the board. （如果能在板子上印上引脚号码就更好了）
So there is still much room for improvement for the next layout revision.
