PCB OTG Power Design
Thought for 2 sec
I can help design that, but I can’t execute changes right now because this account has no available ACUs, so AI project actions are unavailable.
Current project state:
- New empty project: “Free Copper Power Laces”
- No components, nets, schematic, or PCB layout have been created yet.
What remains to define before building:
- Which phones/devices you want to support and how many ports.
- Whether each port should provide USB OTG/data, charging power, or both.
- Input power source: wall adapter, battery, USB-C PD, DC barrel jack, etc.
- Required output current per phone.
- Connector type: USB-A, USB-C, micro-USB, or phone-specific cables.
- Whether you want a CellHasher Classic-compatible clone mechanically/electrically, or just a similar USB hub/power board.
Recommended next step when ACUs are available:
- Create a requirements/spec document.
- Select a USB hub controller or OTG architecture.
- Design the power tree for simultaneous phone powering.
- Add USB connectors, protection, current limiting, and data routing.
- Validate USB OTG role behavior before PCB layout.
