FirstLight Compose · AI hardware design

Design a real PCB from a sentence.

Describe what you're building in plain language. Compose places the parts, routes the board, runs the electrical checks, generates the firmware, and hands you a manufacturable fab package. Minutes, not weeks.

A PCB designed and routed by FirstLight Compose from a plain-language prompt

AI can describe a circuit.
Getting to a board you can build is the hard part.

Schematic ideas are cheap. Turning one into placed, routed, electrically-clean copper with the right parts, firmware, and a fabrication package still means days of manual CAD, or a contract engineer. Compose closes that gap in a single continuous run.

Describe it. Compose builds it. A manufacturable board, checked and ready to order.

How it works

From a prompt to a manufacturable board, in one run.

✓ design✓ placement✓ routing✓ validation✓ erc✓ firmware

A short design interview fills in the details, MCU, radio, power, connectors, with sensible defaults. Then the full pipeline runs in front of you, gated at every stage: nothing ships unless the copper is clean and every net connects.

Manufacturable fab package

Gerbers, drill, pick-and-place, STEP, BOM, accepted by any board house.

Firmware

A compiled, self-test firmware image generated for your board.

FL-1 test plan

A machine-readable probe map with pass/fail limits, ready for hardware validation.

Design and validation are one system. Testability is built in before the board is ever fabricated.

Coming next · FirstLight FL-1

The machine that brings your board to life.

FirstLight FL-1 Desktop with the canopy open, probing a board, the autonomous PCB bring-up and diagnosis station

Compose designs the board. FL-1 validates the physical one. Insert the assembled PCB, press start, and the machine autonomously powers it up, probes it, and tells you exactly what works and what failed, using the test plan Compose generated.

  • Programmable multi-rail power & electronic load
  • Oscilloscope, logic analyzer & DAQ
  • 6.5-digit digital multimeter
  • Automated precision probing & Kelvin 4-wire measurement
  • UART, I²C, SPI, USB, Ethernet, CAN-FD testing
  • Machine vision & thermal inspection

FL-1 is in engineering validation. Reserve your place in line for the first production units.
