The AI Agent for nRF Firmware Engineers
Scaffold, build, flash, and debug nRF52/53/54/70/91 projects from your terminal.
An interactive agent for embedded firmware
Launch fwm agent and land in a full-screen REPL. Slash-commands for everything from /init to /flash, plan/edit/debug modes, datasheet-aware reasoning, and tool-call approvals, all in your terminal.
> curl -fsSL https://firmwaremaestro.com/install.sh | shInteractive AI agent in your terminal
Run fwm agent to open a full-screen TUI with a conversation pane, context sidebar, and 17 slash commands. Ask questions, debug issues, and modify code. The agent reads your project, builds, and flashes in the same session.
Full-screen ratatui TUI
Conversation pane, context sidebar, and tool call log, all visible at once in your terminal.
16 built-in tools
Read, write, and edit code; build and flash; parse datasheets; check Nordic errata; run west and nrfutil.
/plan mode
Read-only exploration before making any changes. Understand the codebase first, modify with confidence.
Inline slash commands
/build, /flash, and /validate run directly in the session, with no context switch.
Session persistence
Resume previous conversations with /resume. Pick up exactly where you left off.
--compliance flag
Enforce safety standards in generated code: MISRA C:2012, ISO 26262, and IEC 62443.
Documentation-driven firmware development
Your AI-generated project docs become the blueprint. The CLI transforms them into real, flashable firmware.
Generate Docs
Use the web app to generate 12 comprehensive firmware documents covering architecture, HAL, protocols, and code scaffolds.
CLI Builds Firmware
The CLI reads your generated docs and produces a complete, buildable firmware project tailored to your target hardware.
Flash to Hardware
One command to flash your firmware. Uses nrfutil and west flash, auto-detected from your nRF Connect SDK project config.
Debug via UART
Monitor real-time UART output from your device. See logs, debug messages, and sensor data live in your terminal.
The complete pipeline
Firmware Maestro bridges the gap between documentation and working hardware. Generate comprehensive project docs in the web app, then let the CLI handle the heavy lifting, from code generation to flashing and debugging. No context switching. No manual translation.
21 Nordic targets, 5 series
Full nRF Connect SDK support across every Nordic nRF family. The CLI auto-detects your hardware and uses west flash for all targets.

Everything the AI agent delivers
A complete firmware development workflow from your terminal: analyze hardware, generate code, flash, and debug.
Datasheet & Schematic Analysis
Feed your datasheets, reference manuals, and KiCad/Altium schematics to the AI agent. It extracts register maps, pin assignments, and timing constraints automatically.
Works with Existing Codebases
Point the agent at your existing firmware project. It understands your code structure, drivers, and HAL layer, then generates new features that integrate cleanly.
AI-Powered Code Generation
The AI agent reads your project documentation (PRD, HAL spec, architecture docs) and produces a complete, buildable firmware project tailored to your hardware.
One-Command Flash
Auto-detects your connected nRF hardware and flashes using nrfutil and west flash, with no manual configuration needed.
UART Debug Monitor
Real-time serial output monitoring built right in. See debug logs, sensor readings, and status messages without leaving your terminal.
Deep nCS Knowledge
Series-aware AI with built-in knowledge of nRF Connect SDK, Zephyr devicetree, Kconfig, SoftDevice, and Nordic errata.
Production-Ready Output
Generated firmware follows MISRA C:2012 guidelines, includes proper error handling, power management, and is optimized for your specific target.
Project Sync (Coming Soon)
Keep your CLI project in sync with the web app. Update docs online, pull changes locally, and regenerate firmware on your own terms.
Real-world validation
Connect to serial interfaces, SWD/JTAG debuggers, logic analyzers, and oscilloscopes to monitor firmware execution in real-time, straight from the fwm REPL.
UART / Serial Monitor
Connect to any serial interface for real-time debug output. Auto-detect baud rate, parse structured logs, and filter by severity level.
Build anything with AI-powered Nordic development
From IoT sensors to complex motor control systems, our AI companion helps you write, debug, and optimize firmware for embedded devices with unprecedented speed and accuracy.
Reads your hardware before writing code
Parses datasheets, KiCad schematics, and your existing codebase to build a complete hardware context.
Generates complete, buildable nRF Connect SDK projects
Zephyr RTOS, Kconfig, devicetree overlays, and peripheral drivers, all wired together correctly.
Series-aware across all Nordic families
Deep knowledge of nRF52, nRF53, nRF54, nRF70, and nRF91, including errata and SDK-specific quirks.
From source to running firmware in one session
Build, flash, and monitor output without leaving the terminal or touching a config file by hand.
Simple, transparent pricing
