Ethernet4pizero: common questions

What microcontroller does the Ethernet4pizero use?

The Ethernet4pizero is built around the SSW-120-01-T-D-006, from the Raspberry Pi family.

How big is the Ethernet4pizero PCB?

The Ethernet4pizero measures 85 × 56 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ethernet4pizero?

25 components, from 16 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 Ethernet4pizero design files?

From the lightside-instruments/ethernet4pizero 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 Ethernet4pizero design in my own project?

Yes, under the terms of its TAPR-OHL-1.0 license, which lightside-instruments chose for the repository.

Can I test firmware for the Ethernet4pizero 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.
