From the project
A 45 × 47.2 mm, 6-layer STM32H743 flight controller designed for navigation in GPS-denied environments via satellite signals of opportunity (SoOP), with native support for standard ArduPilot multirotors and TVC rocket lander avionics.
A 45 × 47.2 mm, 6-layer STM32H743 flight controller designed for navigation in GPS-denied environments via satellite signals of opportunity (SoOP), with native support for standard ArduPilot multirotors and TVC rocket lander avionics.
Autonomous UAVs lose navigation when GPS is degraded or jammed. Optical flow and visual-inertial odometry provide relative velocity and short-term positioning, but accumulate unbounded integration drift over long trajectories.

Iridium drone: common questions
What microcontroller does the Iridium drone use?
The Iridium drone is built around the STM32H743VIT6, from the STM32 family.
How big is the Iridium drone PCB?
The Iridium drone measures 45 × 47.2 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Iridium drone?
168 components, from 72 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 Iridium drone design files?
From the kfilipekk/iridium_drone 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 Iridium drone design in my own project?
The repository has no license, so all rights stay with kfilipekk. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Iridium drone 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.
