The HKT070DTA-1C Topway LCD is a 7 inch smart TFT display module that talks to your controller over a simple serial link, so the screen handles the graphics while your board handles the logic. It is built as a 7 inch RS232 TFT LCD display with 800x480 resolution and a resistive touch panel, which makes it a practical choice for control panels, machine interfaces and engineering graduation projects.

7 Inch RS232 TFT LCD Display With 800x480 Resolution
This 7 inch RS232 TFT LCD display gives you an 800x480 pixel area of 154.08 x 85.92 mm, a larger canvas than the 5 inch version for gauges, charts, buttons and status text on one screen. According to the manufacturer's manual, the panel shows 65k colors (16-bit), reaches a typical brightness of 500 cd/m² and has a typical contrast ratio of 900 (700 minimum). The resistive touch panel responds to a finger, a stylus or a gloved hand.
Industrial Smart TFT LCD Module for Serial Control
As an industrial smart TFT LCD module, the HKT070DTA-1C has a 32-bit MCU on board, so your controller does not need to draw every pixel. You design the screens in advance with the SGTools development tool, load them into the module, and then your controller only sends short serial commands over RS232 to change what is shown. The default serial setting is 115200 bps, 8N1, and projects can be downloaded from a PC or from a USB drive using an OTG cable. This keeps your main code simple and works with any controller that can send serial data, as long as the signal levels match.
Resistive Touch TFT LCD 800x480: Power and Mounting
The resistive touch TFT LCD 800x480 module accepts a supply of 11V to 26V, with 12V as the typical value. Because the minimum is 11V, a 12V supply is the practical choice, and a 5V supply will not work. Before connecting the serial lines to a 3.3V or 5V microcontroller, check the logic level of your controller against the RS232 interface of the module and use a level converter if needed. The casing measures 200 x 125 x 30 mm, and the operating temperature range is -20°C to 70°C.
