Multitool: common questions

What microcontroller does the Multitool use?

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

How big is the Multitool PCB?

The Multitool measures 49 × 49 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Multitool?

68 components, from 34 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 Multitool design files?

From the fmaw/multitool 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 Multitool design in my own project?

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

Can I test firmware for the Multitool 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.
