FligthComputers: common questions
What microcontroller does the FligthComputers use?
The FligthComputers is built around the RP2040, from the RP2040/RP2350 family.
How big is the FligthComputers PCB?
The FligthComputers measures 50 × 72.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the FligthComputers?
131 components, from 52 distinct parts. The full bill of materials is listed on this page.
Where can I download the FligthComputers design files?
From the ManuelRao/fligthComputers repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the FligthComputers design in my own project?
The repository has no license, so all rights stay with ManuelRao. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FligthComputers 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.
