About the Cutiepie2040 PCB

Cutiepie2040 is an open source RP2040/RP2350 PCB design by flamwenco, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 200 × 81 mm, with 105 components from 18 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the W25Q128JVS and XC6206PXXXMR. By type, the board carries 38 LEDs, 38 diodes, 3 ICs, 2 connectors, 1 crystal and 1 switch.

From the project

A funky little 10.5u with dual 1.75u spacebars.

An ortho pcb is also now available as well.

The vial firmware has been updated to visually support uniform stagger, regular stagger, and ortho, but your existing firmware will also work since the pinouts have not changed.

You will also need a daughterboard for this keyboard. It was designed around the ai03 C3 daughterboard.

The case is designed around m2 screws and heatset inserts. The top will need 6 M2x4mm inserts, and M2x5mm screws. The daughterboard mounting in the bottom will need 4 M2x3mm inserts, and M2x4mm screws.

Cutiepie2040: common questions

What microcontroller does the Cutiepie2040 use?

The Cutiepie2040 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Cutiepie2040 PCB?

The Cutiepie2040 measures 200 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cutiepie2040?

105 components, from 18 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 Cutiepie2040 design files?

From the flamwenco/cutiepie 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 Cutiepie2040 design in my own project?

Yes, under the terms of its GPL-3.0 license, which flamwenco chose for the repository.

Can I test firmware for the Cutiepie2040 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.
