From the project
StratoSoar is an engineering project that aims to be able to fly a glider (dropped from a high-altitude balloon), down to any selected coordinates.
TL:DR: The StratoSoar project is a low-cost, lightweight Unmanned Aerial Vechile (UAV) designed for deployment from a weather balloon at various altitudes, aiming for autonomous and efficient flight to designated GPS coordinates. By offering a more affordable, compact, and lightweight alternative to conventional UAVs, StratoSoar aims to empower educators, researchers, and hobbyists with an accessible platform for exploration and experimentation.

SamdFlightController: common questions
What microcontroller does the SamdFlightController use?
The SamdFlightController is built around the ATSAMD21G18A-A, from the Microchip SAM family.
How big is the SamdFlightController PCB?
The SamdFlightController measures 42 × 87.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the SamdFlightController?
106 components, from 69 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 SamdFlightController design files?
From the crnicholson/StratoSoar-MK2 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 SamdFlightController design in my own project?
The repository has no license, so all rights stay with crnicholson. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SamdFlightController without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
