About the Matarael PCB

Matarael is an open source Raspberry Pi PCB design by h3430, published on GitHub. It is a 4-layer board measuring 160 × 90 mm, with 137 components from 56 distinct parts.

Its main chip is the ComputeModule4, from the Raspberry Pi family. Other key parts include the TPD4EUSB30, MagJack-A70-112-331N126, 74LVC1G07SE-7, USB2514B-I/M2 and AP22653W6. By type, the board carries 59 capacitors, 31 resistors, 20 connectors, 16 ICs, 4 diodes and 2 crystals.

From the project

Manet hardware dev

For now, this is in alpha and is still being developed.

What still needs to be figured out: Power delivery PTT? RTC Switch pcie 1x to m.2

Some of the 3d models need to be downloaded form the following places and put into the CM4IO.3shapes directory some models are approximations.

Matarael: common questions

What microcontroller does the Matarael use?

The Matarael is built around the ComputeModule4, from the Raspberry Pi family.

How big is the Matarael PCB?

The Matarael measures 160 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Matarael?

137 components, from 56 distinct parts. The full bill of materials is listed on this page.

Where can I download the Matarael design files?

From the h3430/Matarael repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Matarael design in my own project?

The repository has no license, so all rights stay with h3430. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Matarael without the hardware?

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