Hi, I am actually looking to buy adafruit's lcd below
https://www.adafruit.com/products/2298 for quite some time , but it has been out of stock for almost a month already. And now I'm looking for other options. The main reason I wanted to get that was because there is a GPIO breakout on the LCD and it sort of states which GPIO is used for the LCD so I could wire buttons to free GPIO pins.
But looking elsewhere on china website, I found simliar , but I just do not really know how to read the specs for the GPIO pins. All I want to know is which pins are used for LCD and which are the free ones. For this item

(scroll down for GPIO pin description)
and this item

Actually teaching me how to read these description would also be really helpful.
