Cm4-carrier net: common questions

What microcontroller does the Cm4-carrier net use?

The Cm4-carrier net is built around the DF40HC(3.0)-100DS-0.4V(51, from the Raspberry Pi family.

How big is the Cm4-carrier net PCB?

The Cm4-carrier net measures 90 × 40 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Cm4-carrier net?

17 components, from 14 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 Cm4-carrier net design files?

From the Unlim8ted-Studios/unlim8ted-phone 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 Cm4-carrier net design in my own project?

The repository has no license, so all rights stay with Unlim8ted-Studios. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Cm4-carrier net 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.
