• DNI: don't install.
• SMD 0603 (Imperial) aka 1608 Metric.
• U1 LDO can be replace by RT9193-18GB, change C10 to 22nF.
• U1 LDO can be replace by XC6219B182MR or TLV75519PDBVR
• C1 can 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.
  • R1 should be DNI
  • R2 should be closed (with zero ohm resistor)
  • Pin 2 & 3 should be connecting with a 2.2uf capicator
