Pico-SMSFM: common questions
What microcontroller does the Pico-SMSFM use?
The Pico-SMSFM is built around the Pico, from the RP2040/RP2350 family.
How big is the Pico-SMSFM PCB?
The Pico-SMSFM measures 76.1 × 64.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pico-SMSFM?
31 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pico-SMSFM design files?
From the knight-ryu12/pico-SMSFM repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pico-SMSFM design in my own project?
The repository has no license, so all rights stay with knight-ryu12. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pico-SMSFM 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.
