Verify every active component against datasheets before wiring.
Run schematic review/ERC and fix all violations.
After schematic approval, proceed to PCB placement, routing, and review.
Create product/visual assets such as 3D enclosure renders, dashboard mockups, component catalog images, and investor-style showcase graphics.
Important engineering note: this is a full IoT/agriculture product, not just a simple wiring diagram. The power system, outdoor enclosure, waterproof sensor connectors, pump driver, solar charger, and sensor analog interfaces need to be designed carefully for real farm use.
