ACEBOTT QE027 ESP32 Transportation STEM Kit Assembly Guide

Key Features and Benefits of the ACEBOTT Transportation Kit

The ACEBOTT QE027 ESP32 Transportation STEM Kit delivers an impressive collection of features designed specifically for educational exploration.

The kit leverages the powerful ESP32 microcontroller, which provides sufficient processing capability to handle complex automation logic while remaining accessible to beginners.

The learning benefits extend far beyond basic assembly. By engaging with this kit, learners develop critical problem-solving skills, understand circuit fundamentals, and explore programming concepts through visual block-based coding.

The modular design allows for progressive complexity, meaning users can start with simple streetlight automation and gradually advance to sophisticated traffic management systems.

What's Inside the ACEBOTT QE027 Box 

Understanding the contents helps ensure a smooth assembly experience and prevents missing components before beginning construction.

The kit includes a basswood board serving as the foundation for your streetlamp structure, along with four support frames that provide essential stability. 

The electrical components feature an expansion board that interfaces between the ESP32 and various sensors. An 18650-battery holder powers your system (requiring two 18650 batteries purchased separately), while double-sided tape secures the holder to the base.

For the streetlight functionality, the kit provides an LED module complete with an LED base plate and 3-pin connection lines.  

Steps to Assemble ACEBOTT QE027 ESP32 Transportation STEM Kit 

Step 1: Construct the Foundation Base

Position the support frames at each corner of the basswood board, then secure them with plugs to create a sturdy rectangular foundation. This step establishes the structural integrity of your entire system. 

Key actions for this step: 

• Gather basswood board, four support frames, and four plugs 
• Align support frames perfectly with the mounting holes at each corner 
• Verify the assembly is square and level on your work surface 
• Insert plugs firmly into place without forcing 
• Double-check all corner connections before moving forward 

Step 2: Install the ESP32 Control Board and Expansion Board

Position the three copper columns vertically on the basswood base at designated locations, then secure the ESP32 microcontroller onto these supports. Finally, align and attach the expansion board to multiply your connection options.

Installation process includes: 

• Secure three copper columns to the base using M3×6mm flat-head screws 
• Position ESP32 microcontroller board onto copper supports 
• Align all mounting holes precisely before fastening 
• Seat the expansion board gently onto the ESP32 pins 
• Verify all hole alignments before pressing down completely 
• Apply gentle, even pressure when securing the expansion board 
• Keep track of all fasteners during assembly 

Step 3: Installing the Battery Holder

Clean the underside of your base board to remove dust, then attach the battery holder using double-sided tape. Position it strategically to avoid covering electrical wiring or connection pin holes.

Battery holder installation steps: 

• Clean the underside of the base board with a slightly damp cloth 
• Allow the board to dry completely before proceeding 
• Peel backing from the double-sided tape 
• Position tape on the battery holder surface 
• Adhere the battery holder to the base undersurface 
• Avoid covering any wires or connection pin holes 
• Leave access to the battery compartment for future replacements 
• Press firmly across the entire surface for optimal adhesion strength 

Step 4: Install the Street Lamp Bracket

Assemble the basswood bracket components in the correct order, then position this structure on your base assembly. Ensure the bracket is absolutely vertical using a level for verification.

Bracket assembly guidelines: 

• Stack basswood components in numerical order 
• Use brackets provided to connect components securely 
• Ensure all connections are perpendicular 
• Position the completed bracket structure on the base 
• Secure with plugs provided in your kit 
• Use a level to verify vertical alignment 
• Adjust bracket position if it leans or tilts 
• Verify the bracket is fully seated before proceeding 

Step 5: Install LED Modules

Before touching the LED module, attach the 3-pin sensor cable to the module's connection port. Position the LED base plate at the top of the bracket, then secure the LED module using the provided nuts and screws.

LED module installation details: 

• Connect the 3-pin sensor cable to the module first 
• Position LED base plate at the top of bracket structure 
• Insert M3×12mm round-head screws through base plate holes 
• Thread M3 nickel-plated nuts onto the screw ends 
• Tighten hand-tight plus a quarter turn (avoid over-tightening) 
• Position module straight and level on its base plate 
• Verify the LED module moves slightly when gently pushed 
• Ensure cable has sufficient slack for future routing 

Step 6: Install a Standing Card on the Base

Take the intelligent street light signage card and mount it on your base assembly where it's clearly visible. This serves both aesthetic and educational purposes, helping viewers understand the system's function.

Signage placement recommendations: 

• Position on a clearly visible area of the base 
• Mount on the front-facing side for easy visibility 
• Ensure the card doesn't obstruct functional components 
• Consider angling for improved visibility from typical viewing height 
• Allow adequate spacing so the card doesn't interfere with LED 
• Use foam adhesive blocks if angling the signage 

Step 7: Wiring & Completing the Electrical System

Review your wiring instructions thoroughly before making connections, as incorrect wiring can damage the ESP32 controller. Connect the LED module using the three-pin cable following the exact pin assignments.

Wiring assembly process: 

• Review wiring chart completely before touching any connections 
• Connect LED module signal pin (S) to ESP32 Pin 19 
• Connect LED module voltage pin (V) to 5V power supply rail 
• Connect LED module ground pin (G) to GND connection 
• Route the 3-pin connection cable carefully through bracket structure 
• Avoid placing cables where they might get pinched or damaged 
• Use cable management techniques like gentle twists or routed paths 
• Verify each pin aligns correctly before inserting 
• Double-check all connections before powering the system 
• Understand that incorrect wiring causes permanent component damage 

After wiring verification, insert two 18650 batteries into the holder, and your streetlight system is ready for programming and testing.  

Conclusion 

Completing your ACEBOTT Transportation STEM Kit streetlight assembly marks the beginning of your journey into intelligent transportation systems.

The hands-on experience gained through careful assembly and precise wiring directly translates to understanding real-world IoT applications.

With your foundation established, the kit provides progression pathways to explore advanced concepts like motion sensors, traffic lights, and autonomous control systems.
