ESP32 Scrolling Text LED Matrix Kit - Wi-Fi MQTT Display
ESP32 Wi-Fi Scrolling Message Board Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a Wi-Fi-connected 8x8 LED matrix that displays scrolling messages sent from anywhere using MQTT. Perfect for IoT dashboards, school notice boards, or a custom display for your room. In just a few hours, you'll have a working device that updates live whenever you publish a new text.
What You'll Build
Two daisy-chained MAX7219 matrices form a 16x8 display that scrolls text received over Wi-Fi. You'll write ESP32 code to subscribe to an MQTT topic and update the display in real time. When you send a message via your phone or a simple web app, it appears instantly on the matrix.
What You'll Learn
- Interface MAX7219 LED matrices with SPI on ESP32
- Connect to Wi-Fi and subscribe to MQTT topics
- Program scrolling text animations in C/C++ (Arduino IDE)
- Debug IoT circuits and live message delivery

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring IoT in their computer science projects, B.Tech ECE/EEE freshmen building a mini-project for their first semester, or ATL Tinkering Lab mentors guiding students through real-world IoT applications. Great for Smart India Hackathon participants needing a working display module.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with our AI companion trained on this kit; you can also send a photo of your wiring via WhatsApp for human backup.
Do I need to set up an MQTT broker myself?
No, we'll guide you through using a free public broker or setting up a lightweight broker on your laptop in under 5 minutes.
Can I display my own custom messages from the internet?
Absolutely. Once connected to Wi-Fi and an MQTT topic, any device on the same broker can publish text - your phone, a Raspberry Pi, or a web dashboard.
What if I want a larger display with more matrices?
The kit includes two MAX7219 modules; you can easily daisy-chain up to 8 modules with the same SPI pins, and we show you how to modify the code.
ESP32 drives 8x8 MAX7219 LED matrix over SPI. Shows scrolling text received from MQTT topic.
