Spha gateway hardware: common questions

What microcontroller does the Spha gateway hardware use?

The Spha gateway hardware is built around the Compute_Module_4_Connectors, from the Raspberry Pi family.

How big is the Spha gateway hardware PCB?

The Spha gateway hardware measures 68 × 87 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Spha gateway hardware?

75 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spha gateway hardware design files?

From the sillevl/spha-gateway-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Spha gateway hardware design in my own project?

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

Can I test firmware for the Spha gateway hardware 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.
