STVA050WT-03 is a mid-sized high-luminance TFT LCD Touch Screen Module. 


It is different from the normal TFT module since it intergrades with the CPU, LCD drivers, 128 MB flash memory, and a UART interface for data communication. You can use it as a touch screen controller in many fields even in outdoor applications like energy projects, public transfer system,s or automation projects.



STONE TFT Touch Screen Specifications:


• Cortex m4 CPU;
• UART interface (RS232/RS485/TTL) ;
• 256-byte register;
• 128 kb variable memory;
• 128 MB flash memory, expandable to 1 GB;
• GUI design software;
• The customized command set;
• 8-channel curve trend chart memory;
• extremely fast variable display response speed;
• The single-page supports up to 128 display variables;
• Integrated real-time clock RTC,
• Touch buzzer sound function;
• Support software 90 degrees, 180 degrees, 270-degree screen rotation, adjust the appropriate visual Angle;

STONE TOOL Box(GUI Design software):


STONE TOOLBox (software)


-- Design a group of GUI and using our operational design software to create a project. 

-- Connection by RS232/RS485/TTL Level directlyl. 

-- Write a program for Any MCU to control the Intelligent TFT-LCD Module by using 4pcs simple Hex Instruction.

Facts you need to know:

1. What is the communication protocol for the STONE products?

A: The communication protocol is a customized command set. 

For example:
Setting the number of input data bits is 4 bit, click the "Data entering" button to input "1234 ", click "OK", and the UART returns to the command: 
A5 5A 06 83 00 20 01 04 D2



A5 5A: Frame head
06: command byte length, 83 00 20 01 04 D2 total 6 bytes (without frame header)
83: Read variable register command
00 20: Variable address, set in control properties
              01: Data word length, 04 D2 total 1-word length
04 D2: Data content, 1234 hexadecimal data


2. Can we use the CANBUS/MODBUS protocol to communicate with the STONE product?

A: No. The CANBUS/MODBUS protocol is not supported for now.


3. Can we use Arduino as the controller of the STONE product?

A: Yes. Arduino has the TTL signal pin. You can directly use the STONE display with the TTL interface (please contact our staff to confirm the interface type). Or you can use the MAX3323 chip to converter the TTL signal to the RS232 signal. 

You can check the link to get the specific steps:


4. Can we use Raspberry Pi as the controller of the STONE product?

A: Yes. Raspberry Pi provides build-in/mini UART. They are implemented using different hardware blocks, so they have slightly different characteristics. However, both are 3.3V devices, which means extra care must be taken when connecting up to an RS232 or another system that utilizes different voltage levels.

STONE TECH is working in the TFT LCD display area for over 15 years and has served over a thousand customers all over the world. We have a professional team to handle your technical questions, business issues or other requirements.  



Different from the normal TFT modules, the STONE product is already embedded with a CORTEX M4 CPU and LCD drivers. So you don’t have to re-design the driver or system for the display. This will greatly save your developing cost and time for your project.



The STONE display is using a high-quality component and gets certifications of CE/FC/ROHS/ISO9001. It is stable enough to work in a harsh environment like high/low temperatures, high humidity, or long-time working.
