EEDU Kits offer three ready-to-use hardware platforms for exploring AI, IoT, and environmental sensing with Arduino-compatible programming. Built around the FireBeetle 2 ESP32-E microcontroller (supporting Wi-Fi/Bluetooth), each kit includes application-specific peripherals—enabling rapid prototyping without complex wiring. Ideal for STEAM education, smart home projects, and IoT prototyping, these cost-effective kits feature open-source designs and step-by-step tutorials for all skill levels. 🎥 Video Highlight ⚡ Features ESP32-E Core: 240MHz dual-core processor + 4MB Flash for edge AI tasks (e.g., sensor data analysis). Low-power modes extend battery life for field deployments. Plug-and-Play Peripherals: Audio: DFPlayer Pro MP3 module (128MB storage) + 3W stereo speaker for voice alerts. Sensing: URM37 ultrasonic sensor (2–800cm range), PIR motion detector, and RTC module for time-stamped data. Control: 10A relay for high-power devices (e.g., lights, motors). Expandability: Gravity I²C Hub simplifies adding sensors (e.g., air quality monitors). LED buttons provide tactile feedback for interactive projects. 📊 Specifications Category Details Main Board FireBeetle 2 ESP32-E (SKU: DFR0654) Wireless Wi-Fi 4 (802.11 b/g/n), Bluetooth 4.2 LE Power 5V USB-C input • Supports Li-ion batteries via Gravity connector Relay Capacity 10A/250V AC or 10A/30V DC Ultrasonic Range 2–800cm (URM37 sensor) Audio Storage 128MB (DFPlayer Pro) Interfaces I²C Hub, UART, GPIO pins via Gravity IO Shield 🚀 Applications Smart Campus: Monitor classroom occupancy via PIR sensors + relay-triggered alerts.
