About the Cubeeee 4x4x4 led cube PCB

Cubeeee 4x4x4 led cube is an open source RP2040/RP2350 PCB design by AndrzejKalinowski, published on GitHub under the MIT license. It is a 2-layer board measuring 63 × 63 mm, with 20 components from 11 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. By type, the board carries 8 resistors, 4 transistors, 2 connectors, 2 capacitors, 1 module and 1 switch.

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

From the project

4x4x4 LED cube built on a Raspberry Pi Pico 2 — custom KiCad PCB, SolidWorks mechanicals, and a web control UI served from the cube's own USB drive, no software install needed.

- Designing and fabricating a 4x4x4 multiplexed LED cube - Simple, well-documented project - Eventually a custom PCB - Mechanical and electronics project - Firmware development

The PCB connects the Pico 2 to the hand-soldered LED cube. The LED columns are driven directly from GPIO pins (only one LED is lit at a time), while the layers are switched through N-MOSFETs. A tactile button is added as a 'user interface'. An AUX header exposing GP0/GP1 is provided for future expansion, like sensors. There is also a power-in connector (feeding VSYS), but USB power should be sufficient. The board was…
