SparkFun Optical Tracking Odometry Sensor - PAA5160E1 (Qwiic)

The SparkFun Qwiic Optical Tracking Odometry Sensor empowers your robot's navigation with exceptional precision and streamlined integration. This compact, all-in-one sensor leverages the PAA5160E1 chip from PixArt Imaging Inc., delivering accurate dual-axis motion data across various hard floor surfaces. It also features a built-in 6-axis Inertial Measurement Unit (IMU) and an onboard microcontroller that performs real-time sensor fusion and tracking algorithms.

Measuring just 2.54cm by 2.54cm, this sensor is smaller than its industry counterparts. Unlike bulkier options that require multiple boards, this single-board design includes an onboard tracking algorithm. User-friendly Arduino and Python libraries simplify integration, getting you up and running quickly.

The PAA5160E1 chip offers exceptional tracking with a typical error rate of 3-5% within a working range of 10mm to 27mm. Calibration within the sensor's firmware can reduce this error to under 1% in ideal conditions. It excels at high-speed motion tracking of up to 2.5 meters per second, making it ideal for navigating warehouse robots, commercial robots, and other fast-moving applications.

Thanks to its Qwiic compatibility, this sensor integrates seamlessly into your XRP or other robotics projects. This user-friendly interface eliminates complex wiring configurations and simplifies connection to other Qwiic-enabled components. The included Arduino and Python libraries and the onboard tracking algorithm in the firmware streamline development, allowing you to focus on creating innovative robot functionalities.

Note: This is a CLASS 1 LASER PRODUCT CLASSIFIED IEC 60825-1 2014.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the required PCB space, and polarized connections mean you can’t hook it up wrong.
