it brings down the costfrom 50-60$ to about 13-15

$ .

AS well as remove pullups to 3.3v . as arduino nano is 5v logic

This is only cost saving I am not going to make and sell It saves 35$ off the BOM .
I can produce Gerbers and Pick & Place if Needed.

Note I am using JLCPCB with a low setup cost I am not using a Local Israeli company. If
we have a 500$ NPI the idea is useless. JLCPCB is Limited at 50 PCBS 1250 pcbs.

One can purchase the boards from Aliexpress for about 17-20$ but unknown quality and may
be fake.
