ACEBOTT QE202 ESP32 Advanced Sensor Kit (26-in-1)

This ESP32 Advanced Development Kit (26-in-1) is a project-focused electronics learning kit designed to take you from first LED blink to integrated sensor systems with real-time display and interactive control. The kit centers around an ESP32 controller board and a set of plug-and-play modules connected through an Easy-Plug cabling system, helping beginners build working circuits quickly while still learning the fundamentals of inputs, outputs, timing, and logic. It is suitable for STEM classrooms, makerspaces, and self-learning, and it supports multiple programming approaches including graphical Blockly-style coding, Arduino IDE development, and Python-based learning (exact environment availability may vary by curriculum version).

The ESP32 platform is widely used for modern IoT and embedded projects thanks to its fast MCU, rich GPIO, and built-in wireless capability (Wi‑Fi/Bluetooth features depend on the exact ESP32 module revision on the controller board). In this kit, the controller interfaces with multiple sensor modules (digital and analog-style outputs depending on module design) and output modules such as LEDs, RGB lighting, a traffic light module, and an LCD1602 character display. Typical learning objectives include:

• Digital input reading (buttons, PIR motion triggers, tilt/vibration-style switches depending on module set)
• Analog signal sampling via ADC (e.g., potentiometer, light sensor, sound sensor modules depending on board design)
• Timing and PWM control (LED dimming, buzzer tones, servo positioning where included)
• Distance measurement using ultrasonic time-of-flight (trigger/echo timing concepts)
• Environmental sensing (temperature/humidity module type varies by revision; commonly DHT-class sensors are used in kits)
• Display output via LCD1602 (often I2C backpack or parallel interface depending on module revision; check module labeling/datasheet)

Because the kit is modular, electrical characteristics such as sensor operating voltage, signal levels, and interface type can vary by module revision. The Easy-Plug system is intended to standardize connections and reduce miswiring, but you should still follow the provided tutorial pin maps and module labels for correct port usage.

• Controller platform: ESP32 development board (exact ESP32 variant and flash size varies by revision; check board marking)
• Module count: 26 functional modules (26-in-1)
• Curriculum: 40+ guided lessons/projects (content depth and file formats vary by release)
• Programming support: Blockly-style graphical coding, Arduino IDE, Python (availability may vary by OS and course package)
• Display module: LCD1602 character display (interface varies by module revision; commonly I2C)
• Common sensors included (per kit description): temperature & humidity, ultrasonic distance, sound, flame, PIR motion, light/LED modules, RGB light, traffic light
• Connectivity: Easy-Plug cables/connectors (no breadboard required)
• Power input: typically via USB to the controller board (USB cable included per kit image); exact voltage/current depends on board and connected modules
• Documentation language: English and Chinese (as provided by the course package)

• STEM education and classroom labs: structured progression from simple circuits to integrated systems
• Rapid prototyping: test sensors and displays quickly before committing to a custom PCB/breadboard build
• IoT and automation concepts: motion-triggered lighting, distance alarms, environmental monitoring with local display
• Demonstration builds: compatible with optional mechanical/wooden structure expansion kits (sold separately) for displayable projects

• Follow the kit’s port mapping: Easy-Plug ports may be pre-assigned to specific GPIOs for consistent lessons.
• Mixed-voltage caution: ESP32 GPIO is typically 3.3V logic; some modules may include level shifting or conditioning, while others may not. Use only the intended ports and wiring provided in the tutorial.
• Current draw planning: modules like servos, buzzers, and multi-LED outputs can increase peak current. If you experience resets, power the controller with a stable USB supply and reduce simultaneous high-load outputs.
• Library dependencies: Arduino IDE projects may require installing sensor/display libraries (exact library names depend on module revision). Use the tutorial’s recommended libraries for best compatibility.
• Wireless features: if your lessons include Wi‑Fi/Bluetooth, performance and availability depend on the exact ESP32 board revision and firmware setup.
