About the Plotter PCB

Plotter is an open source AVR/Arduino PCB design by alisha-develops, published on GitHub. It is a board, with 13 components from 10 distinct parts.

Its main chip is the Arduino_Nano_Every, from the AVR/Arduino family. Other key parts include the ULN2003. By type, the board carries 4 connectors, 2 ICs, 2 switches, 2 capacitors, 1 module and 1 diode.

It belongs with the robotics & motion designs in this gallery.

From the project

This is my first hands-on project as a prospective engineer. It is my first PCB built from scratch to explore electronics, motors, and coding. It uses stepper motors controlled by an Arduino to draw patterns on a vertical surface, combining hardware and software in a single system.

Plotter: common questions

What microcontroller does the Plotter use?

The Plotter is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How many components are on the Plotter?

13 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Plotter design files?

From the alisha-develops/plotter repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Plotter design in my own project?

The repository has no license, so all rights stay with alisha-develops. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Plotter 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.
