Overview

BreadPower is an open-source printed circuit board by zeankundev, from the zeankundev/boards repository on GitHub. It is a 2-layer board of 59 × 25 mm with 25 parts on 16 nets, routed with 89 tracks and 6 vias.

It is built around the AMS1117-3.3 and AMS1117-5.0. Its parts include 11 connectors, 3 capacitors, 2 ICs, 2 diodes and 1 resistor.

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 BreadPower PCB?

It measures 59 × 25 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BreadPower use?

25 parts, built around the AMS1117-3.3 and AMS1117-5.0. 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 BreadPower KiCad files?

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

Can I use the BreadPower design in my own project?

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