Hi Bob,

The designs that I looked at OSH are not as feature-rich.

Evil Mad Science is local to me but *unfortunately* they have *not* heeded
to any PCB design rules for their Arduino clone PCB design (see inline
image).

In deed, they have a right Arduino clone outline and are conservative on
USB side (FTDI). I give them a +1 for an attractive mask + overlay as well.

As an engineer I ought to look under the hood though, unortunately.



Please feel free to express your thoughts about this layout as an engineer.


The PCB that I'm looking for is for my friend overseas, as he is getting
his feet wet.
I can send him <$3 Arduino clone from aliexpress
<https://www.aliexpress.com/item/Free-shipping-high-quality-UNO-R3-MEGA328P=

=3D1>
(cheaper then the price of a bare PCB itself) but I would like him to build
one or two for himself.

Anyways, I'll think about working on a clone as time permits.
