hi thanks for sharing the screw shield for arduino mega
I want to know if the screw shield 3.5 is completed and can i order pcbs from jlcpcb?

also i dont want to use the i2c communication , I need only the pin gpio header pin access via screw terminals
can i remove the 10k resistors and 4.7k resistors and c1 ,c2,c3 capacitors?
is there a way i can use the board directly even if i dont connect those capacitors or resistors?
i am really new to all these trying to learn

Hello...
Yes, board design in latest version is "complete".  It is used to drive a robot chassis and does get upgraded from time to time.  Parts are all available on ebay or elsewhere.


You can certainly eliminate the pull up resistors on the I2C lines and the caps on the signal lines are to smooth some noisy analog inputs.  you can drop them too.  i woul dnot advise dropping the caps on the power circuits.


good luck.
