    ELEGOO UNO R4 WiFi Starter Kit and 5PCS Ultrasonic Sensor Bundle for STEM

    • This ELEGOO bundle is built for customers who want a more useful project path than buying a single product alone. ELEGOO 5PCS HC-SR04 Ultrasonic Distance Sensors gives the setup a clear foundation: five HC-SR04 ultrasonic modules for 5V distance measurement, obstacle detection and interactive robot sensing. ELEGOO UNO R4 WiFi Super Starter Kit strengthens that foundation by adding a modern UNO R4 WiFi kit with 48 MHz processor, USB-C, LED matrix, Wi-Fi/Bluetooth and 200+ project components. Together, the two products make it easier to move from a first guided build into hands-on experiments that feel practical, visible and worth repeating. The bundle is especially useful for STEM classes, home learning, maker benches, robotics practice and electronics labs because it supports distance dashboards, obstacle alerts, automation triggers, LED matrix readouts and STEM challenges. Learners can follow the original product resources, then reuse the boards, modules and parts to test new ideas, troubleshoot wiring, compare code behavior and create custom projects. Depending on the selected project, compatible software, libraries, drivers, batteries, external power or extra small parts may be required. Always confirm wiring, polarity, voltage and interface requirements before powering a circuit.
