S

shrey013

@layoutDesign a 2-layer PCB for a hybrid quadcopter + rover robot controller, similar in style to the attached reference (with routed copper view on top and 3D component render below).
PCB Specifications:
Size: ≈ 70 mm × 90 mm (compact to fit inside a 20 cm robot).
Layers: 2 (Top copper = red, Bottom copper = blue, large GND pour on bottom).
Mounting holes: M3 × 4 at the corners.
Required Components:
Microcontroller / Host
Raspberry Pi 4 via 40-pin header
Kakute H7 Flight Controller connection (UART, I²C, power)
Power System
XT30 battery input connectors
4S LiPo input for flight system (with TVS diode + fuse)
2S LiPo input for rover system (with reverse polarity PMOS + TVS + fuse)
Buck converters: MPM3610 / MP1584 (5 V, 3 A)
Large low-ESR capacitor (1000 µF, 35–50 V)
Motor Drivers (Rover)
2 × TB6612FNG (SOIC-16) for 4 DC motors
JST-PH 2-pin headers for motors (LF, LR, RF, RR)
STBY pin routed to GPIO via MOSFET for E-stop
Drone ESC & Motors
Header for 4-in-1 ESC (PWM1–4, GND, VBAT, telemetry)
Sensors
IMU: BNO085 (I²C)
ToF sensors: VL53L1X modules via TCA9548A I²C mux
GPS + Magnetometer header (JST-GH 6-pin)
Pi Camera v3 (FPC connector or external mount)
Alarms & Indicators
Piezo buzzer (5 V)
WS2812 LED header with level shifter (74AHCT1G125)
Connectors & IO
UART header for FTDI / DFPlayer Mini audio module
I²C headers (JST-GH 4-pin)
Encoder inputs (JST-GH 3-pin × 4)
PCB Style:
Top View: routed tracks (red top, blue bottom), copper pours, silk labels.
Bottom View: ground pour and traces.
3D Render: mounted modules shown in different PCB colors:
Raspberry Pi header = black
Kakute H7 interface = green
TB6612 motor drivers = orange
BNO085 IMU = blue
Buck converter = purple
Connectors = white JSTs
Show standoffs, screws, and connectors like in a KiCad 3D viewer.
Output:
Show both PCB layout view (tracks + pours) and 3D assembly render with components."*

I found a section in the Flux documentation that describes the PCB Editor—the interface you’ll use to create your outline, place components, route copper, add pours, and generate 3D views:
Key Components of the PCB Editor
Copilot Menu
The PCB editor integrates with Flux Copilot to provide AI-assisted design capabilities. While Copilot currently has limited understanding of PCB layout (it primarily works with schematics), you can still get help with:
• Understanding layout rules
• Troubleshooting design rule violations
• Learning PCB design best practices
Object Tree
The Object Tree contains a structured map of all the elements present in the PCB editor, from parts to nets to traces.
Inspector
The Layout Inspector panel on the right side shows contextual information about the selected object. When nothing is selected, it shows document-level information like the description, layout rules, and other properties. When a part is selected, it shows contextual information about it.
Source: Flux PCB Editor Reference
If you need step-by-step guidance on specific tasks (outlines, routing, pours, 3D renders), you can explore these resources or let me know which part you’d like to tackle first.
