15-inch 5-wire resistive controller board

This Hetai Tech MT6820 GOLD-A7 board drives 15-inch resistive touchscreen monitors using a 5-wire interface. It suits repair technicians and system integrators who need to replace or add a controller for industrial or legacy displays. The board measures 5.5 by 5.5 centimetres and operates on a 5-volt supply. It is sold as a standalone component without cables or panels.

Universal LVDS support up to 1920 by 1200

The board supports 90 percent of 8 to 42-inch LVDS panels through 25 preset screen modes printed on the reverse side. Maximum resolution reaches 1920 by 1200, but the supplier notes that not all panels are guaranteed compatible. Compatibility depends on matching the panel pinout, voltage and timing exactly. Incorrect wiring can damage the board or the display.

Requires panel knowledge and soldering skill

Installation demands experience identifying the screen cable, resolution and power requirements before connection. The supplier warns that users without maintenance background should not attempt the swap. No programming is needed for supported presets, but mismatched settings lead to a blank screen or hardware failure. Only the controller board is included in the package.

Questions about this item

Which screen size does the 15" version of the MT6820 GOLD-A7 controller board fit?

This board is built for a 15" 5-wire resistive touchscreen and can drive 8-42 inch LVDS panels when the correct screen line and definition are matched.

What resolution can I expect when the board drives a panel in my machine?

The controller supports up to 1920x1200 on compatible LVDS screens, but actual resolution depends on the specific panel you connect.

What interface does the board use and what does it limit in practice?

It uses a universal wide LVDS interface running on 5V power, which caps compatibility to panels that accept 5V LVDS signalling and match the 25 preset screen profiles.
