About the Mega-Cube-Board

Mega-Cube-Board is an open source NXP PCB design by MaltWhiskey, published on GitHub. It is a 4-layer board measuring 200 × 54 mm, with 100 components from 36 distinct parts.

Its main chip is the Teensy4.0_HDR, from the NXP family. Other key parts include the ILI9341, TPS54331DR, C133793 and MAX98357AETE. By type, the board carries 48 resistors, 16 capacitors, 8 ICs, 8 connectors, 1 diode and 1 inductor.

It belongs with the audio and power & battery designs in this gallery.

From the project

16x16x16 PL9823 Cube with Teensy 4.0 and FlexIO driver

Disclamer: These are my own electronic designs. You can use them however you like, but i take no responsibilty for them. It's up to you to use them well.

Versions: 32Bit shift register - This is my first iterration, i had some problems with them due to high frequency signals and using wires instead of pcb traces resulting in reflections. I have changed the software/hardware interface, so these may work, but i haven't tested this.

Mega-Cube-Board: common questions

What microcontroller does the Mega-Cube-Board use?

The Mega-Cube-Board is built around the Teensy4.0_HDR, from the NXP family.

How big is the Mega-Cube-Board?

The Mega-Cube-Board measures 200 × 54 mm, has 4 copper layers and is 1.599998 mm thick.

How many components are on the Mega-Cube-Board?

100 components, from 36 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 Mega-Cube-Board design files?

From the MaltWhiskey/Mega-Cube 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 Mega-Cube-Board design in my own project?

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

Can I test firmware for the Mega-Cube-Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
