Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN-24904:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The SparkFun Qwiic Optical Tracking Odometry Sensor empowers you to elevate your robot's navigation capabilities with exceptional precision and streamlined integration. This compact, all-in-one sensor leverages the power of the PAA5160E1 chip from PixArt Imaging Inc., delivering accurate dual-axis motion data across various hard floor surfaces. But that's not all! This sensor boasts a powerful built-in 6-axis Inertial Measurement Unit (IMU) and an onboard microcontroller that performs real-time sensor fusion and tracking algorithms. The Optical Tracking Odometry board measures a mere 1in. by 1in. and boasts a smaller profile than its industry counterparts. Unlike bulkier options that require multiple boards, this sensor features a single-board design with an onboard tracking algorithm. User-friendly Arduino and Python libraries simplify integration, quickly getting you up and running. The PAA5160E1 chip offers exceptional tracking performance with a typical error rate of 3-5% within a working range of 10mm to 27mm. However, a calibration within the sensor's firmware can significantly reduce this error to under 1% in ideal conditions. This sensor excels at high-speed motion tracking of up to 2.5 meters per second, making it an excellent choice for navigating warehouse robots, commercial robots, and other fast-moving applications. Thanks to its Qwiic compatibility, the SparkFun 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 the development process, 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](https://www.sparkfun.com/qwiic) 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 amount of required PCB space, and polarized connections mean you can’t hook it up wrong.* [Get Started with the SparkFun Qwiic PAA5160E1 Optical Tracking Odometry Sensor Sensor Guide](https://docs.sparkfun.com/SparkFun_Optical_Tracking_Odometry_Sensor)### Features STM32: - Arm® 32-bit Cortex®-M0+ CPU, frequency up to 48 MHz - -40°C to 85°C/105°C/125°C operating temperature - Up to 32 Kbytes of flash memory with protection - I2C address: 0x17 (fixed) Optical Tracking Sensor - PAA5160: - Tracking Accuracy: 3-5% - Tracking speed: 2.5m/s - Working Distance to Tracking Surface: 10-27mm - Frame Rate: 20,000 fps 6-DOF IMU Accelerometer: - ±2/±4/±8/±16 g full scale - ±125/±250/±500/±1000/±2000 dps full scale ### Documents - [Schematic](https://core-electronics.com.au/attachments/localcontent/24904_SparkFun_Optical_Tracking_Odometry_Sensor_Schematic_149085c4223.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/24904_SparkFun_Optical_Tracking_Odometry_Sensor_EagleFiles_22573bfa3ba.zip) - [Board Outline](https://core-electronics.com.au/attachments/localcontent/24904_SparkFun_Optical_Tracking_Odometry_Sensor_BoardOutline_32443ae611b.png) - [Hookup Guide](https://docs.sparkfun.com/SparkFun_Optical_Tracking_Odometry_Sensor) - [Qwiic Info Page](https://www.sparkfun.com/qwiic) - [XRP Info Page](https://www.sparkfun.com/xrp) - [Hardware GitHub Repo](https://github.com/sparkfun/SparkFun_Optical_Tracking_Odometry_Sensor) - [Register Map](https://core-electronics.com.au/attachments/localcontent/OTOS_Register_Map_25590b660d8.pdf) Software Libraries: - [Arduino Library GitHub Repo](https://github.com/sparkfun/SparkFun_Qwiic_OTOS_Arduino_Library) - [Python Package GitHub Repo](https://github.com/sparkfun/Qwiic_OTOS_Py) - [Java Library GitHub Repo](https://github.com/sparkfun/SparkFun_Qwiic_OTOS_FTC_Java_Library) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/S/E/SEN-24904-1.jpg)
