@copilot how do I use Flux?
1y

copilot

Using Flux for designing electronic circuits and PCB layouts is straightforward and efficient. Here's a concise guide to help you get started:
  1. First Steps:
    • Access Flux: Open your web browser and navigate to the Flux.ai website. Log in or create an account if you haven't already.
    • Create a New Project: Once logged in, you can create a new project by clicking on the appropriate option. This will take you to the schematic or PCB layout editor, depending on what you choose to start with.
  2. Designing a Schematic:
    • Place Components: Drag components from the library onto your schematic canvas. You can search for specific components using the search functionality.
    • Make Connections: Once your components are placed, you can draw connections between them using wires. Click on a pin and drag to another pin to connect them.
    • Define Net Properties: Assign net names and characteristics if necessary, by selecting the wire and editing its properties.
  3. Moving to PCB Layout:
    • After finishing your schematic, you can move on to laying out your PCB. Flux automatically transfers your components and connections to the PCB layout editor.
    • Place Components: Initially, all components will be placed outside the PCB outline. You need to drag these onto the PCB, arranging them according to your design requirements.
    • Route Traces: Connect the component pads as per the schematic connections by drawing traces. Flux provides auto-routing functionality, but manual routing is often recommended for optimal control and efficiency.
  4. Review and Export:
    • Examine your design for any errors or improvements. You can also use the design rule check (DRC) feature to automate this process.
    • Once satisfied, export your design. Flux allows you to export schematics, PCB layouts, and Gerber files for manufacturing.
  5. Resources and Support:
    • Documentation: Flux provides detailed documentation, including a getting-started tutorial [1].
    • Community Support: Join the Flux Slack community to ask questions and share experiences with fellow users [2].
    • Video Tutorials: For visual learners, Flux's YouTube channel offers numerous tutorials and example projects [3].
If you encounter any specific issues or have questions as you navigate through Flux, feel free to ask. The platform is designed to be intuitive for users at all levels, from beginners to experienced electrical engineers.

• Power Supply Block provides 5 V and 3.3 V rails to the SoC and peripherals.
• Allwinner H3 SoC is the processing core driving all interfaces.
• LPDDR3 Memory and MicroSD/eMMC Storage attach directly to the SoC.
• USB Interfaces, Ethernet PHY, GPIO Header, HDMI, Camera Interface, and Debug UART/JTAG are the main I/O and expansion ports.

@library find a 5V-to-3.3V LDO in SOT-23-5 with ≥1A output and dropout <200mV

I couldn’t find a SOT-23-5 LDO that meets all of:
  • 5 V→3.3 V
  • ≥ 1 A out
  • Dropout < 200 mV
Most SOT-23-5 parts top out around 0.6 A, or have higher dropout. You have two main options:
  1. Switch to a slightly larger package (SOT-223/SOT-23-6) to get a true 1 A, low-dropout part—e.g., MIC5504-3.3YML (1 A, 170 mV dropout in SOT-23-6).
  2. Parallel two SOT-23-5 LDOs (not ideal for thermal/current sharing).
Let me know if you’d prefer adjusting package constraints (and I can find a SOT-223 or 6-pin SOT part), or exploring alternatives like switching regulators in SOT-23-6.

I can help connect your power rails across the module. To be clear, shall I:
  1. Tie all 5V terminals to a “5V” power net
  2. Tie all GND terminals to the ground net
  3. Tie all 3V3 terminals to a “3V3” net
Let me know if that’s what you’d like, or if you need specific signal nets wired instead.
