README
README.mdDragonFly Flight Controller
DragonFly Flight Controller is an open hardware, low-cost flight controller PCB and experimentation platform for UAV, drone, and embedded systems prototyping. This cost-optimised design uses a two-layer PCB, a budget-conscious bill of materials (BOM), and readily fabricated manufacturing files. Prototype boards were fabricated using the LionCircuits MII service.
The KiCad design targets broad sensor compatibility: it supports most ST LSM6D-series IMUs, while the magnetometer footprint accommodates QMC5883, HMC5883, MMC5983, and IST8310 parts. This makes DragonFly a flexible platform for flight-control experiments, sensor evaluation, and affordable PCB prototyping.
Repository contents
KiCad/Source/— editable V0.1 board, hierarchical schematic sheets, and project settings.KiCad/Production/— PCB and project settings for the releasedwithRibsmanufacturing revision used to generate the production Gerbers.Manufacturing/Gerbers/— production Gerber layers, drill files, drill maps, and KiCad job file.Photos/— photo of the assembled PCB.
Fabrication
Send all files in Manufacturing/Gerbers/ to your PCB fabricator as one fabrication package. The set includes front and back copper, solder mask, silkscreen, paste, board outline, plated and non-plated drill files, drill maps, and the Gerber job file. Confirm your fabricator accepts these Gerber formats and review the generated previews before ordering.
The released board includes an external rib frame (withRibs) for fabrication. Use the matching board in KiCad/Production/ when reviewing this manufacturing package. KiCad/Source/ retains the editable source project from the main V0.1 design directory.
Opening the design
Open KiCad/Source/dragonfly_v0_1.kicad_pro in KiCad to work with the source design. Open KiCad/Production/Dragonfly_v0-1_Ribs.kicad_pcb to inspect the exact released manufacturing board.
Revision notes
The production files are from the V0.1 withRibs release. The original release notes describe it as adding an external rib frame for improved fabrication. Review electrical design, clearances, and fabrication outputs independently before manufacturing or flight use.
