Gearpad: common questions

What microcontroller does the Gearpad use?

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

How big is the Gearpad PCB?

The Gearpad measures 74.6 × 124.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gearpad?

80 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gearpad design files?

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

Can I use the Gearpad design in my own project?

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

Can I test firmware for the Gearpad 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.
