OPENWAVE 2350: common questions

What microcontroller does the OPENWAVE 2350 use?

The OPENWAVE 2350 is built around the RP2350A, from the RP2040/RP2350 family.

How big is the OPENWAVE 2350 PCB?

The OPENWAVE 2350 measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OPENWAVE 2350?

55 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the OPENWAVE 2350 design files?

From the MAHESH-THILAK-K/ADDITIONAL-PROJECT 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 2350 design in my own project?

Yes, under the terms of its Apache-2.0 license, which MAHESH-THILAK-K chose for the repository.

Can I test firmware for the OPENWAVE 2350 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
