Inav osd: common questions
What microcontroller does the Inav osd use?
The Inav osd is built around the STM32F103CBTX, from the STM32 family.
How big is the Inav osd PCB?
The Inav osd measures 16.9 × 21.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Inav osd?
40 components, from 27 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 Inav osd design files?
From the iNavFlight/inav-osd repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Inav osd design in my own project?
Yes, under the terms of its MPL-2.0 license, which iNavFlight chose for the repository.
Can I test firmware for the Inav osd 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.
