About the Panel PCB

Panel is an open source RP2040/RP2350 PCB design by zeankundev, published on GitHub. It is a 4-layer board measuring 90 × 65 mm, with 72 components from 24 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the ADP7142AUJZ-3.3, GD25Q16CEIGR and ESP8266EX. By type, the board carries 18 capacitors, 7 resistors, 5 ICs, 4 connectors, 2 crystals and 2 diodes.

It belongs with the power & battery designs in this gallery.

From the project

A collection and an archive of KiCad projects I made. Contains projects from 2023 - 2024.

- 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…

Panel: common questions

What microcontroller does the Panel use?

The Panel is built around the RP2040, from the RP2040/RP2350 family.

How big is the Panel PCB?

The Panel measures 90 × 65 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Panel?

72 components, from 24 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Panel design files?

From the zeankundev/boards repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Panel design in my own project?

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

Can I test firmware for the Panel without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
