FP Interface Card: common questions
What microcontroller does the FP Interface Card use?
The FP Interface Card is built around the Pico, from the RP2040/RP2350 family.
How big is the FP Interface Card PCB?
The FP Interface Card measures 90.2 × 101.1 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the FP Interface Card?
263 components, from 110 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 FP Interface Card design files?
From the Sierra-Lobo/fp-pib-hw repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the FP Interface Card design in my own project?
The repository has no license, so all rights stay with Sierra-Lobo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FP Interface Card 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.
