From the project

PMW3901MB Optiocal Flow Sensor Module designed with KiCAD

The EngEmil PMW3901MB Module is a Optical Motion Tracking Chip module, for optical position control of drones. The PCB module is designed with KiCAD 9.

Version 2 - Removed 3v3 regulator and changed VCC pin text to 3V3 - Added ESD protection - Added reverse voltage protection - Added pull-up resistors for SCLK and MISO. Marked as not mounted. - Added resistor for RC-filter for PMW3901MB. Marked as R4=0ohm, and C3 and C4 not mounted. Note added in schematic.
