LPMS-U3
The LPMS-U3 is a miniature 9-axis IMU / AHRS with multiple wired interfaces. A 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer drive high-speed orientation and relative displacement measurements. An on-board 32-bit DSP handles sensor fusion at up to 500 Hz.
Key features
- USB, RS232, TTL, and CAN-Bus connectivity
- 9-axis sensor fusion with low drift and high-speed output
- Temperature and barometric pressure sensors for altitude
- Miniature form factor: 34 × 34.5 × 15.7 mm, 17.6 g
- Configurable via LPMS-Control2
- CANopen support (CU3 variant)
Variants
- LPMS-CU3 - USB 2.0 + CAN Bus
- LPMS-URS3 - USB 2.0 + RS232
- LPMS-UTTL3 - USB 2.0 + TTL / UART
All three variants share identical 9-axis sensors, on-board sensor fusion, and plastic OEM enclosure - choose by host-side interface.
