CalcPad-V2: common questions

How many components are on the CalcPad-V2?

18 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the CalcPad-V2 design files?

From the Preston02000/CalcPad-V2 repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the CalcPad-V2 design in my own project?

The repository has no license, so all rights stay with Preston02000. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CalcPad-V2 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.
