PAW3395 PCB
PixArt PAW3395DM-T6QU low power laser mouse sensor breakout board.
- Compatible to PAW3950DM-T5QU.
- 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-paw3395-driver and zmk-paw3950-driver

- DNI: don't install.
- SMD 0603 (Imperial) aka 1608 Metric.
U1LDO can be replace by RT9193-18GB, changeC10to 22nF.U1LDO can be replace by XC6219B182MR or TLV75519PDBVRC1can be replace by 3.3uF.- For PAW3395 Option
- PAW3395DM-T6QU needs to be used with compact LOAE-LSI1 lens, or chonky LM19-LSI lens.
- For PAW3950 Option
- PAW3950DM-T5QU needs to be used with compact LOAE-LSI1 lens, or chonky LM19-LSI lens.
R1should be DNIR2should be closed (with zero ohm resistor)- Pin 2 & 3 should be connecting with a 2.2uf capicator
