About the Dso 26 PCB

Dso 26 is an open source RP2040/RP2350 PCB design by codingdestro, published on GitHub. It is a 2-layer board measuring 139.1 × 118.3 mm, with 54 components from 4 distinct parts.

Its main chip is the RP2040_Zero, from the RP2040/RP2350 family. Other key parts include the TRRS. By type, the board carries 26 switches, 26 diodes and 2 ICs.

It belongs with the keyboards designs in this gallery.

From the project

An ergonomic split keyboard for engineers.

A custom mechanical keyboard PCB designed in KiCad 8.

Both are independent KiCad projects sharing the same design settings.

The project references an external footprint library configured in fp-lib-table:

- Lily58 — Lily58 keyboard footprints (${KIPRJMOD}/../../Lily58/pcb/Lily58-footprint.pretty)

Pre-generated PCBWay production files are available in top-plate/pcbwayproduction/`.

Dso 26: common questions

What microcontroller does the Dso 26 use?

The Dso 26 is built around the RP2040_Zero, from the RP2040/RP2350 family.

How big is the Dso 26 PCB?

The Dso 26 measures 139.1 × 118.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dso 26?

54 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dso 26 design files?

From the codingdestro/dso_26 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dso 26 design in my own project?

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

Can I test firmware for the Dso 26 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.
