About the Untitled PCB

Untitled is an open source RP2040/RP2350 PCB design by dj505, published on GitHub. It is a 2-layer board measuring 78.7 × 40.2 mm, with 70 components from 38 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the ESP-12F, NCP1117-3.3_SOT223, W25Q32JVSS and USBLC6-2SC6. By type, the board carries 24 capacitors, 15 connectors, 12 resistors, 7 switches, 6 ICs and 5 diodes.

It belongs with the wearables, displays & leds and dev boards & breakouts designs in this gallery.

From the project

A badge thing

I figured since it was going to have a screen, I needed to be able to use the screen for something, so I included hardware I was already familiar with to interface with. There's the RP2040 I've used in other previous projects, and I've played with the ESP8266 before in the context of Arduino-like programming, so I thought I would try integrating that into this design so I could play with the AT firmware a little. I've used WS2812B LEDs a ton and thought they'd make a good set of indicators. And, since I wanted this to be versatile, it features some screw holes as well as slits along either…

Untitled: common questions

What microcontroller does the Untitled use?

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

How big is the Untitled PCB?

The Untitled measures 78.7 × 40.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Untitled?

70 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Untitled design files?

From the dj505/Untitled repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Untitled design in my own project?

The repository has no license, so all rights stay with dj505. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Untitled 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.
