For the pet feeding device, I ordered boards from OSHpark with the “After Dark” style. This colour combination of the black substrate with the copper and transparent solder mask is just beautiful.
I made this post just in case you did not see the pictures on Twitter or like to see them with a better resolution.
If you have any questions, missed information, or simply want to provide feedback, feel free to comment below or contact me on Twitter. 😄
