Epson IMU M-G330PDG UART/SPI

Epson IMU M-G330PDG UART/SPI

PDG seriesEntry model

The entry model of Epson's PDG series: a factory-calibrated 6-axis IMU for robots, AGVs and machines at a sensible cost.

Same 24 × 24 × 10 mm, 10 g footprint as the higher-performance PDG models, so your design can grow with your product.

Applications

Where the M-G330PDG fits best

Robots, AGVs and AMRs

Heading and tilt to support odometry and SLAM in service and logistics robots.

Agricultural and construction machines

Attitude for guidance, levelling and implement control.

Low-cost UAVs and UGVs

Stable attitude where the navigation filter gets frequent GNSS updates.

Motion tracking

Orientation and vibration capture in industrial equipment.

Performance

Allan deviation and key specifications

For systems that fuse the IMU with odometry, SLAM or GNSS, the M-G330PDG offers solid stability at the lowest cost in the series.

FAQ

Frequently asked questions

Is the M-G330PDG accurate enough for my robot?

For robots and machines that fuse the IMU with wheel odometry, SLAM or GNSS, 3 °/h bias instability is usually sufficient. If the IMU has to carry heading alone for longer periods, a higher PDG model is the better choice.

Can I upgrade later without a redesign?

Yes. The M-G330PDG, M-G366PDG and M-G370PDG share footprint and connector.

Which interfaces are supported?

UART or SPI; one of the two is connected.

Can I borrow an evaluation kit?

Yes, for qualified projects we lend an evaluation kit free of charge.
