Overview

TutorialPCB is an open-source printed circuit board by zeankundev, from the zeankundev/boards repository on GitHub. It is a 2-layer board of 32 × 30 mm with 23 parts on 44 nets, routed with 263 tracks and 24 vias.

It is built around the ATMEGA32U4-AU. Its parts include 8 resistors, 6 capacitors, 3 diodes, 3 connectors and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.

zeankun.dev's KiCad Boards Repository

A collection of folders for all of my KiCad projects. Archived projects also go here. Go take a look if you want to explore

Prerequisite

You will need:

KiCad 8.0 (do not use nightly builds) or later
git

Just clone the repo. That's it.

git clone https://github.com/zeankundev/boards.git

Directory explanation

Most of the projects you see here often orientate around microcontrollers. If you want an even more detailed one, you can read the listing here.

Pico2040 and Pico2350 series. These are my self-designed boards oriented mostly around ARM microcontrollers. especially the RP2040 and the RP2350
LiPower, BreadPower and LCDRucksack. Those are two board categories that I like to classify them as being "useless". LiPower being the overengineered version of the TP4056 charger, BreadPower being the most generic breadboard power supply. Of course, this was designed before I even know USB-C PD. LCDRucksack is just literally a clone of the LCD backpacks out there, but with castellated holes.
ProyekOPSI2023 was the board I designed for the Indonesian research competition OPSI, in which I participated. There are two variants; the main is one contains an integrated MCU, being the ATMega328P, while the other one requires you to solder on a Pico2040 R2 Wireless by yourself.

Have fun, LOL. Dig in on my archive. I might try to update more if I have a board to design. Anyways, cya.

Questions

How big is the TutorialPCB PCB?

It measures 32 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the TutorialPCB use?

23 parts, built around the ATMEGA32U4-AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the TutorialPCB KiCad files?

From the zeankundev/boards repository on GitHub, at the commit this page was made from: the board is TutorialPCB/TutorialPCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the TutorialPCB design in my own project?

Its repository states no licence, so its author keeps all rights: ask zeankundev before reusing the design.

Category and platform
