D01Flight-controller board

Estimate motion and command the four motors.

Manufacturers & products

The flight controller combines the processor, motion sensor and interfaces that run the flight software. Board firmware support and power interfaces matter more than the processor label alone.

American sourcing options appear first. A U.S. company or distributor label does not establish U.S. manufacturing. The origin notes identify the specific evidence and any limits.

manufacturer

Rotor Riot / Unusual Machines

Brave F7

Complete FPV controller with plug and solder-pad interfaces, integrated IMU, barometer and analog OSD. [1][2]

U.S. manufacturing claim

Rotor Riot explicitly states Brave F7 production in Orlando, Florida. This is a board-manufacture claim, not proof that its MCU, sensors or every material are US-origin. [1][2]

Program / application

5-inch freestyle candidate; original RR2144-01 revision [1][2]

Published manufacturing site: Orlando, Florida, USA

Online catalog / ordering

Official product page provides a catalog or inquiry route; verify current stock, revision, firmware and connectors before ordering.

Product scope & qualifications

Original product page and newer V2 listings coexist; do not transfer firmware notes or specifications between revisions.
The original page specifies Betaflight 4.5.1. Confirm current firmware support with the exact revision.

manufacturer

ModalAI

VOXL 2 Mini

Integrated flight controller and companion computer for compact autonomous aircraft. [3][4]

U.S. manufacturing claim

The specific VOXL 2 Mini product page states assembled in the USA; origin of Qualcomm and sensor silicon is not thereby established. [3][4]

Program / application

Compact UAS/autonomy alternative; extra integration versus a freestyle stack [3][4]

Published manufacturing site: USA

Online catalog / ordering

Official product page provides a catalog or inquiry route; verify current stock, revision, firmware and connectors before ordering.

Product scope & qualifications

Flight Core v2 is end-of-life; its retained documentation is not a current product recommendation.
An autonomy platform does not provide a drop-in Betaflight stack or complete radio/video system.

manufacturer

Holybro

Kakute H7 V2

Complete H7 FPV controller with Bluetooth configuration, OSD, barometer and onboard regulators. [6]

U.S. connection unverified

The consulted product page establishes the manufacturer and board, but not a production location; no US-origin claim is assigned. [6]

Program / application

5-inch freestyle candidate; verify stack height and harness pinout [6]

Online catalog / ordering

Official product page provides a catalog or inquiry route; verify current stock, revision, firmware and connectors before ordering.

What remains unverified

No complete all-US semiconductor bill of materials is established.
Source claims do not establish available stock or interchangeable revisions.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Firmware and board target
Confirm support for the exact board revision and desired flight software.
Stack pattern and clearance · mm
Board outline, USB access and connector height must fit the frame.
Input voltage and transient tolerance · V
Check battery-input rating and regulator architecture for the selected 6S system.
Peripheral power budget · A
Add camera, receiver, GNSS and video loads against each regulated rail.
Sensor and vibration isolation
Compare the installed IMU, mechanical isolation and sensor-bus arrangement.
Serial and motor interfaces
Count usable UARTs after internal peripherals and verify the ESC protocol and pinout.
Logging and serviceability
Blackbox memory and accessible pads help diagnose a civilian freestyle build.
Origin and revision traceability
Board assembly, chip fabrication and firmware provenance are different evidence layers.

Selection & integration notes

Match the firmware ecosystem before choosing hardware.
Check wiring pinouts rather than trusting a shared connector shape.
Retired hardware is kept out of the current supplier shortlist.

Brave F7 RR2144-01Rotor Riot / Unusual Machines

Input: 3–8S LiPo[1]Published board input range; does not assign the same tolerance to accessory pads.
Board / mounting: 37 × 37 mm / 30 × 30 mm[1]Original product page wording; verify mechanical drawing for the current revision.
Mass: 8 g[1]Board figure; wiring and accessories add installed mass.

The 6S illustrative build falls within the stated input range; this is not a complete compatibility approval.
