Key 1 is a "test" button that I plan to use to prime this thing. There is a DC 5.5 x 2.1 plug for a 12V 1A DC adaptor in top left. The components on the right will be exposed from the enclosure for user feedback, and the JST XH connectors are for the sensors. I figured you guys love this stuff and it is second nature to you, so I am all ears for any general feedback, criticism, and design improvements in general that I will take to my future PCB design endeavors and use this one. I learn by doing and iterations, so here goes. I am a complete novice to this, but I think that the design is close. This should actuate servos to control water flow to "zones" based on the feedback from the sensors of soil wetness. (Side note: I wasn't looking forward to switching at first, but the component selection with included pattern was a real treat with EasyEDA compared to Diptrace). I used Diptrace initially, but then switched over to EasyEDA since I plan to send it to JLCPCB for the best cost and all their components from LCSC have the included the PCB footprint. So, this is my first mostly SMD PCB with standalone ATMEGA328P-PU on a PCB at least. I wanted to do this one that way as well, but realized it would have been a bear to make DIY and mostly THT wasn't the direction to go. Just designed my first "real" PCB that I plan to send out for manufacture in the next day or so.
