FlexKey: common questions

What microcontroller does the FlexKey use?

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

How big is the FlexKey PCB?

The FlexKey measures 345 × 124 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the FlexKey?

253 components, from 13 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 FlexKey design files?

From the dushyantyadav0303/FlexKey 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 FlexKey design in my own project?

Yes, under the terms of its MIT license, which dushyantyadav0303 chose for the repository.

Can I test firmware for the FlexKey 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.
