: This is the switch signal. It must be connected to a 3.3V–5V signal to turn the backlight on.
Mechanical dimensions: Typically 21.5mm (L) x 11.5mm (W) x 6.8mm (H), with 2.54mm pin spacing suitable for breadboards or perfboards. gyd-9e datasheet
Given the lack of specific information on the "GYD-9E," let's assume it's a hypothetical electronic component. : This is the switch signal
: For repairs or power handling, the original ME15N10 MOSFET is sometimes swapped for alternatives like the AP15N03. gyd-9e datasheet
