Simpleflightcontroller: common questions

What microcontroller does the Simpleflightcontroller use?

The Simpleflightcontroller is built around the STM32F722RETX, from the STM32 family.

How big is the Simpleflightcontroller PCB?

The Simpleflightcontroller measures 40 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Simpleflightcontroller?

79 components, from 37 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 Simpleflightcontroller design files?

From the notaroomba/simpleflightcontroller 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 Simpleflightcontroller design in my own project?

The repository has no license, so all rights stay with notaroomba. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Simpleflightcontroller 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.
