Product Requirements Document (PRD)
Comprehensive document defining what your firmware product needs to do — functional requirements, non-functional requirements, power budgets, user stories, and acceptance criteria.
Why It Matters
A clear PRD prevents scope creep, aligns your team, and gives AI coding tools the context needed to generate accurate firmware code. It's the foundation every embedded project needs.
What's Included
How It's Generated
AI Research
Gemini with Google Search Grounding researches current SDK documentation, API references, and best practices for your specific hardware platform.
Document Generation
GPT-5.1 generates a comprehensive PRD using the research context, tailored to your project requirements and hardware.
Review & Edit
Review the generated document, make edits directly, or use AI refinement to adjust specific sections with custom instructions.
Export & Use
Download as part of your project bundle. The document integrates with all other generated docs and code scaffolds.
Other Document Types
Architecture Doc
High-level system design showing how firmware modules interact — task architecture, communication patterns, memory layout, and dependency maps with Mermaid diagrams.
Learn moreHAL Doc
Defines the interface layer between your firmware application and hardware peripherals — GPIO, SPI, I2C, UART, ADC drivers with clean API definitions.
Learn moreState Machine
Formal definition of your firmware's state machine — states, transitions, guards, actions, and error recovery paths visualized with state diagrams.
Learn moreContext Bundle
Machine-readable JSON file containing all project context — hardware specs, pin mappings, library versions, and configuration — optimized for AI coding tools to consume.
Learn moreBootloader/OTA
Complete specification for the device bootloader, firmware update mechanism (DFU), and over-the-air update flow — memory partitioning, image signing, and rollback strategy.
Learn moreImpl Plan
Phase-by-phase development roadmap breaking the firmware project into sprint-sized work packages with dependencies, milestones, and effort estimates.
