Flight Engineer — Power Distribution Board
About the Flight Engineer — Power Distribution Board
Flight Engineer — Power Distribution Board is an open source PCB design by Stab-Rabbit-coding, published on GitHub under the CERN-OHL-W-2.0 license. It is a 4-layer board measuring 90 × 65 mm, with 115 components from 44 distinct parts.
By type, the board carries 3 inductors, 3 capacitors, 1 fuse and 1 diode.
From the project
A functional, security conscious, Unmanned Aerial Vehicle based on the Firefly Class spacecraft Serenity from the 2002 show..
This directory holds the KiCad projects for the four cape/board types:
Per-board net/pin documentation lives in the matching .md files (Pilot.md, TACCO.md, FlightEngineer.md, XCVR-49MHZ-2.md). KiCad files keep KiCad board coordinates (documented exception to the hull-frame standard, see root AGENTS.md).
A pass was made to wire in a second Ethernet channel and to clear the Design-Rule-Check (DRC) and ratsnest issues introduced by a manual component rearrangement. This section records exactly what landed and what is still open, so the thread can be picked up cleanly.
