Spooky FC — Custom INAV-Compatible Flight Controller
Spooky FC Custom Flight Controller Spooky FC is an STM32 based flight controller designed for drone. The main goal of this project is learning, testing, and exploring flight controller design. Since this design allows modification and experimentation (**untested changes may cause unpredictable drone behavior.**) Please proceed carefully, especially if you’re new to custom FC hardware. Spooky FC is INAV-compatible and uses the STM32F405RGT6 microcontroller, and to improve stability we use on board IMU which is ICM-42688-P known as a high-performance 6-axis MEMS motion sensor.

Great work! This is really polished, and I think should work without issue. Just a couple thing to do though! Add your shipping option/show number of boards being ordered in your cart screenshots, + use .csv for your bom (not a .xlsx file!), individually upload each file of your pcb instead of a zip, make some preliminary code(just try figuring out what kind of code you need and try your best :D ), and also detail your journals more! Right now they just say that you did "x" and "y" and show the final product. Include how you got there - what design choices did you have to go through, what did you learn, etc!

Look like a really cool project!
But you have to change some stuff first :
You should export more files from easyEDA, like the schematic JSON and DRC rules
Also your BOM needs to be in a . CSV format
Also if possible use economic PCBA parts.
It would be also nice if you uploaded the details of the PCB and pricing of the PCB in your screenshots, not just the PCBA
Excited to see the final result

Made the Cover
Made this cool cover that emphasize on all the feature and also present the render of Gerber file aka printed circuit board which are rendered in black soldermask color.

Spooky FC PCB Routed & Silkscreen Completed 🎃
Finally,
I’ve successfully completed the routing of Spooky FC and carefully checked the PCB’s integrity to make sure there are no shorts, missing connections, or critical design issues. Routing under a strict time limit was challenging, but it really pushed me to stay focused and efficient.
Along with routing, I also finished designing the silkscreen layer. All component names, orientations, and important markings are now clearly placed, making Spooky FC much easier to assemble, debug, and test later on. Clean and readable silkscreen is something I didn’t want to compromise on, even within this tight timeline.
With routing, integrity checks, and silkscreen design completed, Spooky FC is now fabrication-ready. Making this much progress within 24 hours feels incredibly rewarding and keeps the momentum strong for the next steps.

MAJOR UPDATE
Finished making schematics YES I have finished making schematic's now i have exported this project to kicad because i feel comfortable in KiCad to route the pcb.

A challenge for myself
With this project i am taking a challenge to make schematics and route a pcb within next 24hr.
from this i can evaluate my skills and technical ability.
in my benefit i already knew how stm and mcu works
PS: WISH ME LUCK
