SparkFun Experiential Robotics Platform (XRP) Controller

The Experiential Robotics Platform (XRP) Controller lets you build and program your own robot using tool-free hardware, Qwiic connectivity, wireless control, and multi-language coding.

The Experiential Robotics Platform (XRP) is a hands-on, comprehensive robotics platform. It includes everything needed to build and program a robot to perform beginner through advanced tasks - building the foundation for innovative thinking, science, engineering, and problem-solving. The platform focuses on four pillars:

* Hardware Kit: Easily assemble a robust and expandable robot platform with tool-free construction and versatile integration for sensors and actuators.

* Programming Environment: Utilise a multi-language coding experience with Blockly, Python, and WPILib, providing a user-friendly interface for all skill levels.

* Online Modules and Projects: To master robotics concepts, follow a structured learning path with engaging challenges and comprehensive resources.

* Technical Forum: Access community-driven support, expert assistance, and collaborative opportunities within a dedicated technical forum.

The SparkFun XRP Controller is significantly improved over the Beta XRP Controller! It features a Raspberry Pi® RP2350B dual-core processor; 16MB of flash and 8MB of PSRAM; low-power accelerometer + gyroscope 6-DoF IMU (LSM6DSOX from STMicroelectronics®); two Qwiic® connectors for easy integration of sensors and accessories; two dual-channel motor drivers for four motors total; four servo headers; a user button; a full-colour RGB LED, and more. Wireless connectivity is available via a Raspberry Pi® RM2 radio module, enabling 2.4GHz WiFi and Bluetooth for remote control and IoT projects. The Controller Board now features a pair of 2x20 expansion headers that allow for even more customization, either through existing and future expansion boards or your custom additions. These headers connect to nearly all the usable pins on the RP2350 and RM2, so some are shared between the other connectors (motors, sensors, etc.). Make sure to take care when using these shared pins. The inner row of the expansion header matches the pinout of a Raspberry Pi Pico 2 (except for the analog-to-digital pins); users can plug Pico accessory boards into those connectors, with some exceptions. The Qwiic connectors offer endless customisation possibilities. This simple interface makes adding sensors and accessories easy, allowing you to tailor your robot's capabilities to your needs. No soldering is required to connect it to the XRP Controller! The XRP Controller Board caters to all skill levels. Choose from beginner-friendly Blockly or dive deeper with Python. Even FIRST® Robotics enthusiasts can program their creations using familiar tools. With multiple programming options available, the possibilities are truly endless.
