Overview
Panel is an open-source printed circuit board by zeankundev, from the zeankundev/boards repository on GitHub. It is a 4-layer board of 90 × 65 mm with 260 parts on 292 nets, routed with 2,004 tracks and 436 vias.
It is built around the RP2040, ESP8266EX and GD25Q16CEIGR, with the ADP7142AUJZ-3.3-R7 among its other parts. Its parts include 72 capacitors, 28 resistors, 20 ICs, 16 connectors and 8 diodes. It belongs with the ESP8266 and RP2040 boards of this library.

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.gitDirectory 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.
Pico2040andPico2350series. These are my self-designed boards oriented mostly around ARM microcontrollers. especially the RP2040 and the RP2350LiPower,BreadPowerandLCDRucksack. 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.ProyekOPSI2023was 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 Panel PCB?
It measures 90 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Panel use?
260 parts, built around the RP2040, ESP8266EX, GD25Q16CEIGR and ADP7142AUJZ-3.3-R7. 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 Panel KiCad files?
From the zeankundev/boards repository on GitHub, at the commit this page was made from: the board is Pico2040-Modular-Rev3-W/panel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask zeankundev before reusing the design.
