# Flysky ST16 Hardware Mod for Complete touch Support

This touch screen modification can only be used under the edgetx system and cannot be applied to the flyskyos system.

Adding a touch screen will occupy the wiring of the two rear buttons, thereby affecting the functionality of those two buttons.

## Touchscreen assembly

The materials required for screen assembly

[![Screen_assembly_components](../assets/images/hw/flysky-st16/Screen_assembly_components.png)](../assets/images/hw/flysky-st16/Screen_assembly_components.png)

Place the inner screen inside the screen frame, and have the wires pass through the gap.

[![Screen_installation](../assets/images/hw/flysky-st16/Screen_installation.png)](../assets/images/hw/flysky-st16/Screen_installation.png)

Then place the touch glass outside the screen frame, and have the wiring pass through the gap.

Connect the 6-pin touch cable to the FPC cable, and then connect the 40-pin cable.

[![FPC_connection](../assets/images/hw/flysky-st16/FPC_connection.png)](../assets/images/hw/flysky-st16/FPC_connection.png)

Use tape to fix the fpc to the back of the outer frame.

[![Placement_of_FPC](../assets/images/hw/flysky-st16/Placement_of_FPC.png)](../assets/images/hw/flysky-st16/Placement_of_FPC.png)

Put the screen assembly back into the remote control and insert the screws to connect the wires.
