How To Buy
The USB Expansion Board is now being manufactured by our partners at Redshift Labs, and can be purchased directly from Redshift or from Pololu.
The USB expansion board allows the UM7 or GP9 to be connected directly to your computer. Comes with either a 6-pin, two-sided cable compatible with the GP9, or a 5-pin, two-sided cable compatible with the UM7. Also comes with a 6 foot USB A to mini-B cable.
The expansion board provides +5.0V out to power the UM7 or GP9 directly from the USB bus.
Extra cable assemblies can be purchased here.
- 5-pin cable assembly length: 6″
- Output: 3.3V TTL UART
- Max current output on +5.0V output: 100mA
- CHR Serial Interface
- You may need to install these drivers: FT232 Virtual COM Port Drivers

UM7-LT Orientation Sensor
The UM7-LT is equivalent to the UM7, except that it does not include an enclosure and factory calibration is not available. The UM7 is a 3rd-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates.
