Roboy crazyfly: common questions
What microcontroller does the Roboy crazyfly use?
The Roboy crazyfly is built around the STM32F405, from the STM32 family.
How big is the Roboy crazyfly PCB?
The Roboy crazyfly measures 80.2 × 80.2 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Roboy crazyfly?
108 components, from 44 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 Roboy crazyfly design files?
From the Roboy/roboy_crazyfly repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Roboy crazyfly design in my own project?
Yes, under the terms of its BSD-3-Clause license, which Roboy chose for the repository.
Can I test firmware for the Roboy crazyfly without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
