STVA043WT-01 is a high-luminance intelligent TFT LCD module.


STONE provides an Intelligent HMI solution. The intelligent serial TFT LCD display with a Cortex-M4 32-bit CPU can be controlled by any MCU via simple Hex Instruction through the UART port.

The module consists of a CPU, TFT drives, flash memory, UART port, power supply, etc. STONE also provides a basic control program and powerful design software (STONE TOOL Box). You can use it to set various functions on the graphical user interface, such as text, figures, curve, image switching, keyboard, progress bar, the slider, dial-up, clock and touch button, data storage, the USB download, video, and audio.

It is very easy for engineers to develop the TFT-LCD color user interface and touch control functions, which can reduce a lot of development time and cost. 



Dimensional drawing:





•   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
•   Customized command set
•   Support backlight brightness adjustment, automatic standby screen saver function;
•   Single page supports up to 128 display variables;
•   Support hardware JPG decoding, storage more efficient, faster display;
•   File name naming rules are simple, and there is no need to correspond to Flash block Numbers, nor do the tedious manual allocation of Flash blocks.
•   Integrated real-time clock RTC, 
•   Touch buzzer sound function;



Q: What kind of interface does STONE use to connect with the control device?

A: All STONE product is using UART serial interface (RS232/RS485/TTL) to connect with the control device. 
The other interface such as HDMI, SPI, RGB, etc. is not available for the STONE products right now.


Q: Is the STONE product sunlight readable?

A: Yes. The STVA series product is a high luminance model (1000 cd) and sunlight readable.


Q: Does the STONE product include a bezel/case/enclosure?

A: Yes. We have plastic/metal/IP65 (water, dust, oil proof) bezel available as accessories.


Q: What is the touch screen type of STONE product?

A: We have resistive touch, capacitive touch, and non-touchscreen display available.


Sample for developing:

For example: Show integer "1234 ", the UART returns the command: 
A5 5A 05 82 00 20 04 D2 



A5 5A: Frame head 
05: command byte length, 83 00 20 04 D2 total 5 bytes (without frame header) 
83: write variable register command 
00 20: Variable address, setting in control properties 
04 D2: Data content, 1234 hexadecimal data
