About the Pcb project

Pcb project is an open source RP2040/RP2350 PCB design by EvilOtter222, published on GitHub. It is a 2-layer board measuring 110 × 60 mm, with 62 components from 24 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the W25Q128JVS, AP2112K-3.3 and PAM8302AAD. By type, the board carries 23 capacitors, 17 resistors, 10 switches, 6 connectors, 4 ICs and 1 transistor.

It belongs with the power & battery, audio and dev boards & breakouts designs in this gallery.

This is my first PCB ever. I've done a lot of embedded stuff before (Arduino, Picos, ESP chips) and I built an 8-bit breadboard computer, but everything I've made was on breadboards and protoboards. I had never opened PCB software before this.

The idea came from a handheld I made with an ESP32 and a capacitive touch TFT (my reddit post a year ago: https://www.reddit.com/r/arduino/comments/1r4qdw3/breakoutgamewithtftand_arduino/). I wanted to build something like that again, but with everything on one board, so the RP2040 goes straight on the PCB. I picked the RP2040 because it's cheap, it's…

Pcb project: common questions

What microcontroller does the Pcb project use?

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

How big is the Pcb project?

The Pcb project measures 110 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb project?

62 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 Pcb project design files?

From the EvilOtter222/pcb-project repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Pcb project design in my own project?

The repository has no license, so all rights stay with EvilOtter222. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pcb project 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.
