Drone electronics · designed in Ohio
Every chip accounted for.
Power modules, ESCs and flight controllers for small drones, designed for U.S. fabrication and assembly, with the wafer fab and packaging site of every active chip on the record.

Why provenance
A U.S. brand is not a U.S. part.
From 2027, U.S. defense sourcing rules for small drones look past the logo: where each board was fabricated, and where each chip was made and packaged. Most board makers can't tell you what's inside their boards. We design ours so we can.
If a part can't show where it was fabricated and packaged, it doesn't go on a Ferrowing board.
Our standard
What every Ferrowing board carries
One rule set, applied to every design before a board is ordered.
01
Provenance on the record
Wafer fab and packaging site for every active part, published per production lot. Unknown origin never passes.
02
U.S. boards
Bare boards from U.S. fabricators, assembled and tested in Ohio.
03
Open autopilots
Built to work with PX4 and ArduPilot. Any firmware we write lives in a U.S.-controlled repository.
04
Checked before it's built
Every design passes an independent electrical rule check and a written requirements list before fabrication.
Boards
The stack, starting with power
We're starting where the risk is lowest and the proof is fastest: the power module. The ESC and the flight controller follow on the same standard.
