About the Dream-Keyboard PCB

Dream-Keyboard is an open source RP2040/RP2350 PCB design by rushabh69, published on GitHub. It is a 2-layer board measuring 320 × 152 mm, with 151 components from 10 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the SOIC-14_3.9x8.7mm_P1.27mm. By type, the board carries 72 diodes, 67 switches, 6 capacitors, 2 ICs, 2 resistors and 1 connector.

It belongs with the keyboards and displays & leds designs in this gallery.

From the project

KiCad project for the keyboard PCB. 65% layout with an encoder cluster, hotswap sockets, RGB and an OLED. Raspberry Pi Pico as the controller, one 1N4148 diode per key.

Matrix: 5 rows × 15 cols. Pin mapping (matches firmware/keyboard.toml):

Parts / footprints to add (marbastlib for the keyboard parts):

- Hotswap sockets — Kailh MX hotswap footprint (marbastlib SWMX1u hotswap variant), not soldered switches. - Encoder — EC11 rotary encoder footprint; A/B to GP20/GP21, encoder push wired into the matrix at (row0, col14). - RGB — SK6812 MINI-E LEDs chained (DIN→DOUT), data from GP22, plus…

Dream-Keyboard: common questions

What microcontroller does the Dream-Keyboard use?

The Dream-Keyboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the Dream-Keyboard PCB?

The Dream-Keyboard measures 320 × 152 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dream-Keyboard?

151 components, from 10 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 Dream-Keyboard design files?

From the rushabh69/Dream-Keyboard 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 Dream-Keyboard design in my own project?

The repository has no license, so all rights stay with rushabh69. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dream-Keyboard 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.
