1.8 tft different shields

hi everyone,
I tested SKU:MAR1801 red tft shield with small size SD card and LCDwiki_GUI and LCDwiki_SPI libary
http://www.lcdwiki.com/1.8inch_Arduino_SPI_Module_ST7735S_SKU:MAR1801
its workerd,
but me interested if I install libary Adafruit_ST7735 и Adafruit_GFX
can be real worked and connect with same board but another libary,
or others shields are equipped with different 1.8 TFT displays?

for example, pins

SKU:MAR1801 shield small sd card - VCC, GND, GND, NC, NC, NC, CLK, SDA, RS, RST, CS (board use TRANSCEIVER WITH 3-STATE OUTPUTS LVC245A)

red shield with big size sd card have some pins - LED, SCK, SDA, A0, RESET, CS, GND, VCC
blue shield big size sd card - RST, CS, D/C, DIN, CLK, VCC, BL, GND

All three displays should work with Adafruit_ST7735. You might need different INITR_xxxTAB defines in the initR() function.

The SKU.MAR1801 board will accept 5V logic and is write-only.
The other two boards require 3.3V logic and are read-write. (very few libraries implement read functions)

Regardless of what Ebay adverts say, they might contain a different controller to ST7735S

A0 = DC = RS ... just different names for the same pin.
