Hello everyone I am working on Open Source SBC Board with RK3576 & LPDDR5

Anyone want to work me on it
I working on kicad and this is what I made for now

🤖 In the meantime, here’s a response from the [FEDEVEL AI HW Assistant]().
It helps to find relevant resources for your question, but it may make mistakes as it’s still in early development.

This is the response from the AI Assistant:
For complex SBC designs like your RK3576/LPDDR5 board, here are key insights from our hardware design videos that may help:

1. **Collaboration Strategy**
KiCad supports team workflows through:
- Plain text file formats that work with Git (enables version control and distributed collaboration)
- Symbol/PCB library management improvements in v6 for consistency
- Ability to divide schematic pages between team members

2. **Critical Design Considerations**
For LPDDR5 implementation:
- Follow Rockchip's layout guidelines strictly (length matching, impedance control)
- Use KiCad's constraint manager for high-speed rules
- Plan for 100+ hours just for memory subsystem layout based on similar projects

3. **Finding Collaborators**
Effective approaches include:
- Sharing progress on hardware communities like Fedevel Academy forums
- Breaking project into subsystems (power delivery, DDR, peripherals)
- Using GitHub with clear contribution guidelines

**Key Resources**
- Request RK3576 reference schematics directly from Rockchip
- Use JLCPCB's SMT library for component selection
- Implement BMC-like monitoring for production boards

For specific DDR5 routing challenges or power integrity analysis, consider sharing screen captures of your current layout - the community often provides valuable feedback on signal topology and decoupling strategies.

I noticed the feedback pins on pmic sheet are grounded, is that intentional?

yes
