Chip pin layout diagram

DPI setting of mouse chip: DPI pin, used to set the value of DPI, the following is divided into three situations to introduce the use of DPI pin.
1200 DPI setting: this state is the default state, the internal pull-up resistor method is used, or an external 51K ohm pull-up resistor can be connected. When the IC is powered on, check the status of this pin and find that no external level is connected or an external 51K ohm pull-up resistor is connected, set the internal DPI to 1200. Typical application circuit diagram, as shown in the figure below Show:

The electrical parameters of the wireless mouse:

Description:
1: During the mouse PCB layout process, the distance between the IC ground pin and the capacitor ground should be as short as possible, and the ground wire should be as copper as possible
2: In DPI applications, during dynamic switching, the other end of the button is grounded and cannot be connected to a 5V power supply
