AgXRP Starter Kit - DIY - Beta

Turn your desk into a smart farm with this DIY open-source agricultural robotics kit designed for hands-on STEM education, encouraging customisation and 3D printing of your unique frame.


Description

Imagine a classroom where students do not just read about the future of agriculture, they build it. The DIY AgXRP Starter Kit is an open-source, autonomous robotics platform that bridges the gap between STEM education and sustainable farming. By providing the core electronics and encouraging you to 3D-print your own frame, this kit offers an accessible system that turns complex precision agriculture into an engaging, hands-on learning experience. Students will gain practical skills in programming, data analysis, and automation as they design, build, and optimise their own small-scale smart farms.

This kit goes beyond basic robotics by providing an interdisciplinary curriculum that integrates robotics, precision agriculture, and horticultural science, enabling students to tackle real-world farming challenges.

  • Custom Smart Farms: Learn about robotics, agriculture, and 3D printing by constructing your own automated plant care system.
  • Data-Driven Growth: Utilise data analysis, capacitive soil sensors, and peristaltic pumps to optimise crop growth and completely automate watering cycles.
  • Open-Source Access: Gain full access to all 3D printable files, a comprehensive parts list, and detailed assembly instructions to build and modify your system.

As technology in modern farming advances, it’s essential that educational tools evolve to prepare the next generation of farmers to meet global food demands. From coding sensors to optimising harvest cycles, this kit equips students to explore automation, sustainability, and data-driven agriculture, all while growing their own food and deepening their understanding of the technology shaping our future.

Educator Discount Available: SparkFun and its partners are proud to work closely with the education community. We offer a significant discount on the AgXRP Starter Kit with an Educator account! Please contact support@sparkfun.com to get started.

Hands-On Agricultural Automation

This DIY version of the AgXRP Kit includes the essential electronic hardware and tubing to create a functional, automated plant-care station. However, this economical version does NOT come with a physical frame. You can use our open-source files to 3D-print the enclosures and structural supports yourself!

The SparkFun XRP Controller serves as the brain of your farm, coordinating incoming sensor data and managing the timing of your automation cycles. It features a Raspberry Pi® RP2350B dual-core processor preprogrammed with AgXRP firmware; 16MB of flash and 8MB of PSRAM; a 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; 0.1in. headers for electrical expansion possibilities, 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.

Instead of just observing a plant, students actively build the systems that keep it healthy.

  • Automated Watering: Students construct a custom peristaltic pump using the Hobby Motor with Encoder, Deep Groove Ball Bearings, and the AgXRP Single Pump Enclosure. This allows for the precise delivery of water through the included Latex Tubing.
  • Accurate Soil Monitoring: The SparkFun Qwiic Soil Moisture Sensor connects to the controller via a Flexible Qwiic Cable to provide real-time data on exactly when a plant needs hydration.
  • DIY Structural Support: You will 3D print the AgXRP frames and enclosures to provide a stable (and potentially custom) foundation for your electronics during long-term experiments.

Looking to expand your setup? You can add up to three AgXRP Pump & Soil Moisture Sensor Expansion Packs to your DIY AgXRP Starter Kit, allowing you to automate and monitor four independent planting zones at the same time.

Collaborative STEM Ecosystem

To ensure this platform prepares students for real-world challenges, we partnered with organizations driving actual change in communities nationwide. This includes leading academic institutions such as Cornell University and the University of Idaho.

Because this is a Beta release, we are actively looking for educators, students, and community partners to help shape its future. Whether you want to pilot the AgXRP, contribute to curriculum development, or support broader outreach efforts, you are joining a growing community dedicated to building the future of food, one line of code at a time.
