Questions
How big is the Ismd flight computer PCB?
It measures 143 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ismd flight computer use?
47 parts, built around the TEENSY 4.1, BMP580, BMP581 and DPS310XTSA1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ismd flight computer KiCad files?
From the EmmardFr/Drone-Project repository on GitHub, at the commit this page was made from: the board is hardware/ismd_flight_computer (obselete)/ismd_flight_computer-backups/ismd_flight_computer-2026-05-27_163352/ismd_flight_computer.kicad_pcb and its schematic hardware/Carrier_PCB/Carrier_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ismd flight computer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
