9.4 PCB Layout Consideration

1. Caps for pins 5, 8, 9, 10 must have trace lengths less than 5mm.

2. The trace lengths of OSCOUT, OSCIN must less than 6mm.

3. Avoid the eye safety issue, please placement the R1_1 ~ R1_5 and VR1 in a straight line and avoid any resistor

to short each other or short to VCC.

4. Avoid the eye safety issue, please guard the trace from LD’s cathode to mouse sensor’s PIN2 (LD) and avoid

short to ground.
