D02Inertial measurement unit

Measure angular rate and acceleration.

Manufacturers & products

The IMU senses rotation and acceleration. Most freestyle users buy it already integrated on a flight controller; the upstream chip directory explains that supply-chain layer.

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

Analog Devices

ADIS16470

Factory-calibrated six-axis industrial IMU for embedded motion sensing. [3][4]

U.S. company

Analog Devices lists Wilmington, Massachusetts corporate headquarters. The consulted ADIS16470 source does not establish fabrication or assembly origin. [3][4]

Program / application

Upstream industrial IMU; larger integration alternative, not a tiny FC-chip substitute [3][4]

Company location: Wilmington, Massachusetts, USA

Manufacturer inquiry

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

manufacturer

TDK InvenSense

ICM-42688-P

Compact six-axis motion sensor used upstream in flight-controller designs. [5][6]

U.S. company

InvenSense identifies its headquarters in San Jose, California. TDK branding and a US office do not establish US manufacture of the die or package. [5][6]

Program / application

Upstream IMU IC; requires supported board and firmware integration [5][6]

Company location: San Jose, California, USA

manufacturer

Bosch Sensortec

BMI270

Compact accelerometer/gyroscope with programmable filtering and data rates. [7][8][1][2]

International supplier

Manufacturer datasheet identifies Bosch Sensortec in Reutlingen, Germany; the product's factory location is not established. [7][8][1][2]

Program / application

Upstream reference documented on FPV controllers; manufacturer product-use restrictions apply [7][8][1][2]

Company location: Reutlingen, Germany

Manufacturer inquiry

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

Product scope & qualifications

BMI270 datasheet §9.2 excludes air and safety-critical applications. Documented use by an FC maker is not Bosch approval; resolve intended-use terms with the responsible suppliers.

What remains unverified

No identical-condition test dataset compares these sensors as installed in a 5-inch quad.
Package origin, wafer fab and lot-specific traceability need manufacturer documentation.

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

Supported driver and bus
An electrically compatible sensor still needs firmware support and an appropriate SPI/I2C implementation.
Gyroscope full-scale range · °/s
Avoid clipping rapid rotation while preserving useful resolution.
Accelerometer range · g
Choose a range consistent with vibration and maneuver loads.
Noise density and bandwidth
Noise figures must be compared at equivalent operating and filter settings.
Sampling rate versus loop rate · Hz
Sensor output rate alone does not define usable control-loop bandwidth.
Bias and temperature behavior
Static calibration and temperature drift are separate from random noise.
Package and mechanical mounting
PCB strain, vibration and orientation affect installed measurements.
Origin and traceability
A US sensor company does not imply a US-fabricated die.

Selection & integration notes

Select a tested controller/firmware combination before attempting custom sensor integration.
Keep measurement range distinct from absolute maximum shock ratings.

Gyroscope noise density: 2.8 mdps/√Hz[5]Advertised product value; consult datasheet mode and filtering conditions.

Noise density is not a flight-controller attitude-accuracy claim.
