Hardware Description of 3.97 Inch Parallel-Port Display Module

10.1 raspberry pi screen

The module hardware supports 8-bit and 16-bit parallel port data bus mode switching (as shown by the red box in Picture 1 above), as follows:

Solder R3 and R4 with 0Ω resistor or short circuit directly, and disconnect R2 and R6: select 16-bit data bus mode (default), use DB0~DB15 data pin
Solder R2 and R4 with 0Ω resistor or short circuit directly, and disconnect R3 and R6: select 8-bit data bus mode, use DB0~D7 data pin
