Wave: common questions

What microcontroller does the Wave use?

The Wave is built around the RASPBERRY_PI_2_3, from the Raspberry Pi family.

How big is the Wave PCB?

The Wave measures 88 × 88 mm, has 2 copper layers and is 1.600198 mm thick.

How many components are on the Wave?

157 components, from 50 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 Wave design files?

From the Libre-Talk/Wave 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 Wave design in my own project?

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

Can I test firmware for the Wave 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.
