Thought for 2 sec
I can’t generate or add the requested render right now because this workspace has no available ACUs, so AI execution tools are unavailable.
Current project state:
- Project was just created.
- No components, nets, schematic, PCB layout, or render have been added yet.
- Your prompt describes a detailed concept for a 135 × 70 mm DIY smartphone-style mainboard with STM32H750, LTE, USB-C charging, boost power, audio, camera/display connectors, buttons, and black ENIG PCB styling.
What remains to be done once ACUs are available:
- Generate the visual PCB concept render from your prompt.
- Optionally turn the concept into an actual Flux schematic and PCB layout plan.
- Define the real electrical architecture: power tree, battery charging/protection, LTE power requirements, display/camera pinout, MCU I/O allocation, and board stackup.
Define power tree
Create schematic plan
Set board requirements
Check custom parts
To get started, talk to Flux or create a New Document.
