WALLOPS_RED_GEN/README.mdWALLOPS
Wide Angle LiDAR Laser Operating in Pressurized Space
Part of College of the Canyons' RockSat 2026 Payload that will be integrated onto a NASA Wallops Sounding Rocket
Connects to a Raspberry Pi 5 on the Machine Learning Suite board.
Goal is to collect distance data from 4 VL53L8CX 8x8 near infrared sensors to translate into point cloud and recreate pressurized payload on sounding rocket, as well as generate the parts of the payload (e.g. backs of mounted objects) that cannot be observed by the scan using machine learning.

Questions
How big is the WALLOPS PCB?
It measures 55 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WALLOPS use?
33 parts. 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 WALLOPS KiCad files?
From the dsp-mark/PCB_Backups repository on GitHub, at the commit this page was made from: the board is WALLOPS_RED_GEN/WALLOPS.kicad_pcb and its schematic 555_Circuit/555_Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WALLOPS design in my own project?
Its repository states no licence, so its author keeps all rights: ask dsp-mark before reusing the design.
