Questions
How big is the Io v2-Board PCB?
It measures 45.7 × 90.3 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Io v2-Board use?
81 parts, built around the ESP32-S3-WROOM-1-N16R2, LD39150DT33-R, RFM95W-915S2 and SAM-M8Q-0. 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 Io v2-Board KiCad files?
From the Maeswoon/UNHSEDS repository on GitHub, at the commit this page was made from: the board is Engineering/Avionics/Io-v2/Io-v2-Board/Io-v2-Board.kicad_pcb and its schematic Archive/Engineering/2022-2023 Rocket/Avionics/Io_Design/v1.0/Io.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Io v2-Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask Maeswoon before reusing the design.
