OpenWave: common questions

What microcontroller does the OpenWave use?

The OpenWave is built around the STM32F405RGT, from the STM32 family.

How big is the OpenWave PCB?

The OpenWave measures 40 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenWave?

51 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the OpenWave design files?

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

Can I use the OpenWave design in my own project?

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

Can I test firmware for the OpenWave without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
