KRUPS-FemtoSat: common questions
What microcontroller does the KRUPS-FemtoSat use?
The KRUPS-FemtoSat is built around the PICO_2_W, from the Raspberry Pi family.
How big is the KRUPS-FemtoSat PCB?
The KRUPS-FemtoSat measures 29.2 × 71.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the KRUPS-FemtoSat?
32 components, from 22 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 KRUPS-FemtoSat design files?
From the krups/RockSatX-GHOST-Hardware 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 KRUPS-FemtoSat design in my own project?
The repository has no license, so all rights stay with krups. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the KRUPS-FemtoSat without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
