PMW3610 PCB

PixArt PMW3610DM-SUDU low power laser mouse sensor breakout board.

• Base on schematic from siderakb/pmw3610-pcb.
• Be operated with 3.3V voltage level ONLY.
• Outlined as narrow as possible for side mount horizontally and perpendicular on low profile keyboards.
• Developed for zmk-pmw3610-driver

• DNI: don't install.
• SMD 0603 (Imperial) aka 1608 Metric.
• PMW3610 needs to be used with LM18-LSI lens.
• R1 is optional/additional RESET pull up resistor, RESET pin of PMW3610 has a built in weak pull up circuit.
• U2 LDO can be replace by RT9193-18GB, change C10 to 22nF.
• Solder extra decoupling capacitors (C4, C6, C7) directly to the pins of the sensor, if needed.
