Waterboard: common questions

What microcontroller does the Waterboard use?

The Waterboard is built around the C2961140, from the RP2040/RP2350 family.

How big is the Waterboard PCB?

The Waterboard measures 9.4 × 9.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Waterboard?

72 components, from 17 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 Waterboard design files?

From the invicta952-dotcom/Waterboard 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 Waterboard design in my own project?

The repository has no license, so all rights stay with invicta952-dotcom. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Waterboard 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.
