GreenhouseWateringSystemV1: common questions

What microcontroller does the GreenhouseWateringSystemV1 use?

The GreenhouseWateringSystemV1 is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the GreenhouseWateringSystemV1 PCB?

The GreenhouseWateringSystemV1 measures 78 × 58 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the GreenhouseWateringSystemV1?

75 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the GreenhouseWateringSystemV1 design files?

From the BRoughley488/GreenhouseWateringSystemV1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the GreenhouseWateringSystemV1 design in my own project?
