Hi All, does anyone has seen or worked with this TFT display board?






The seller claims that is **GC9A01** driver board but i doubt it. I tried every example i can find including the GC9A01, ST7789, ST7735 libraries but nothing happens except the backlight is turning on and of.
Another thing that i found it weird is that all other board that they [sell](https://fr.aliexpress.com/item/1005005802513979.html?src=google&aff_fcid=3a9497fd07c64ccc893571e6aa4e62f8-1704228928955-07624-UneMJZVf&aff_fsk=UneMJZVf&aff_platform=aaf&sk=UneMJZVf&aff_trace_key=3a9497fd07c64ccc893571e6aa4e62f8-1704228928955-07624-UneMJZVf&terminal_id=06909bf218f644128f47d3dfc5c7cee9&afSmartRedirect=y) have the pinout:


**- RST**
\- **CS,**
\- **DC,**
\- **SDA,**
\- **SCL,**
\- **GND,**
\- **VCC**
\- **(+/- BLK)**


But mine (the red one) has:


**- LED(same as BLK)**
\- **SCK**
\- **SDA -**
\- **A0/DC** (this one especially weird, i think is used to select between command and data modes**),**
\- **RESTART,**
\- **CS,**
\- **GND,**
\- **VCC**


The other (TF-\*) i believe are for the SD card reader.


Any help is welcomed, im using Arduino nano if that helps it to narrow it down.

 

This link may help.

Thanks Jon.

The only thing that i was able to figure out is the correct pin usage:

**- LED(same as BLK)**
\- *SCK* - Same as SCL/SCLK
\- *SDA -* - Same as DIN
\- *A0/DC* -
\- *RESTART,*
\- *CS,*
\- *GND,*
\- *VCC*

Even though i used the library that is recommended in the tutorial im still getting a blank screen...
Ive tested both on the Arduino nano and on nodeMCU but still no luck.

Do you have any other suggestions?
