Sofle Pico: common questions

What microcontroller does the Sofle Pico use?

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

How big is the Sofle Pico PCB?

The Sofle Pico measures 145.4 × 116.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sofle Pico?

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

Where can I download the Sofle Pico design files?

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

Can I use the Sofle Pico design in my own project?

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

Can I test firmware for the Sofle Pico 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.
