Some sensors and devices need 3.3v, they cannot run on 5v

Alternative : can add voltage regulator (AMS1117-3.3 / NCP1117ST33T3G)

Every time we need to take a look at schematic or PCB we have to open the complete project in KiCad.
So why not just adding 2-3 images of each screen, that would make it easier to check the circuit whenever necessary.

add i2c logic level converter circuit for blue robotics pressure sensor

Do the basic switching simulation for mosfet

remove solder mask from high current traces wherever necessary

there is some error in board outline
few labels are out of board

OVER-CURRENT PROTECTION
adding resettable fuse for limiting the current through batteries

check the capacitor placement in datasheet

check if needed, might not need if we power with USB

which network switch to use and how to power it ?
preferably select something with input supply ranging 5-12v

remove the blocking text from pads (text on silk screen layer prints above the pad and creates problem while soldering)
