About the SmartPlant PCB

SmartPlant is an open source AVR/Arduino PCB design by aleksul, published on GitHub under the MIT license. It is a 2-layer board measuring 48 × 75.3 mm, with 32 components from 23 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. Other key parts include the L7805 and DS1307ZN+. By type, the board carries 12 resistors, 4 connectors, 4 capacitors, 2 ICs, 2 modules and 2 switches.

From the project

SmartPlant is a simple project that will help you automate watering of your plants.

SmartPlant is a simple project that will help you automate watering of your plants.

Simple and industrial design is easy for 3d printing. Look at this beauty:

Custom PCB will polish the look of the final product and make assembling even more simple and fun.

You can edit any part of this project with open source software such as

- KiCad for schematics and PCB design, - FreeCad for 3d modeling, - Arduino IDE for code.

SmartPlant: common questions

What microcontroller does the SmartPlant use?

The SmartPlant is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the SmartPlant PCB?

The SmartPlant measures 48 × 75.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SmartPlant?

32 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the SmartPlant design files?

From the aleksul/SmartPlant repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SmartPlant design in my own project?

Yes, under the terms of its MIT license, which aleksul chose for the repository.

Can I test firmware for the SmartPlant without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
