SOFTWARE
We need two code bases. One Zephyr application that runs on the GCS PCB (PCB APP). And one Python Raspberry Pi app (RPI APP) for displaying and managing the telemetry data.
PCB APP
Specs:
- Zephyr
- Talks with rocket and pad control through brage over CAN FD
- USB CDC to send data to RPI. Choose appropriate serialization format.
- Sends valve toggle position only when send button has been pressed.
- Shows status of valve on led.
RPI APP
Specs:
- Data to show:
- Analog
- With plot:
- Altitude
- Thrust. From loadcell.
- Orientation (from IMU) (not priorty)
- Airbrake percantage
- Without plot (only value):
- Speed
- Battery voltage
- Tank temperature. 6 ones spread over the tank.
- Injector temperature
- Post-combustion chamber temperature. 2 ones.
- Nozzle temperature. 2 ones.
- Pressure at injector. 3 ones.
- Misc.
- (GPS map if time over)
- With plot:
- Discrete/bool:
- Tank full float switch. (full/not full)
- Parachute line cutters. 2 ones.(fired or not dired)
- umbilical disconnect (connected or disconnected)
- Analog
- Gets binary data stream from GCS PCB. Hugo will help with protocol pack/unpack. See wiki comparison of serialization formats. Maybe choose Protobuf or similar?
- Log data in text file. save periodically
- Use dearpygui for displaying data
electronics venv
to activate python venv. have uv installed and execute
uv venv --system-site-packages
uv pip install -r pyproject.tomlParts

Questions
How big is the Freyja gcs pcb PCB?
It measures 300 × 200 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Freyja gcs pcb use?
306 parts, built around the SN65HVD232DR-JSM, IP2721, RY3730 and SY8368AQQC. 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 Freyja gcs pcb KiCad files?
From the aesirkth/freyja-gcs repository on GitHub, at the commit this page was made from: the board is electronics/freyja-gcs-pcb/design/freyja-gcs-pcb.kicad_pcb and its schematic electronics/freyja-gcs-pcb/design/7seg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Freyja gcs pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask aesirkth before reusing the design.
