ESP32 Mesh Chat Network Kit with ESP32 + LED
ESP32 Mesh Chat Network Kit — Self-Healing WiFi Mesh for Text Messaging
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a communication network that works without a central router—three ESP32 boards connect directly to each other, forming a self-healing mesh. Type a short text message using a tactile button on one board, and it instantly appears on the OLED displays of all three units. This kit turns you into a mesh networking engineer in under five hours, giving you a real-world understanding of decentralised IoT communication.
What You'll Build
You'll assemble and programme three ESP32 nodes that wirelessly connect in a mesh topology. Each node has its own 0.96-inch OLED screen and a button for text entry. Once programmed, the network automatically discovers peers and relays messages—even if one node goes offline, the others maintain communication through self-healing.
What You'll Learn
- Configure ESP32 boards as mesh network nodes without a router
- Programme the painlessMesh library for self-healing WiFi communication
- Interface OLED displays using the I2C protocol
- Debounce tactile buttons and manage text input efficiently

Who This Kit Is For
Perfect for CBSE Class 11-12 students building computer science or physics projects, B.Tech ECE/EEE first-years exploring embedded systems, and Smart India Hackathon participants prototyping mesh networks. ATL Tinkering Lab innovators and engineering aspirants from IIT, NIT, VIT, or BITS will value the hands-on IoT experience. Basic Arduino familiarity is enough to get started.
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 to chat with your AI companion, which knows this exact mesh network build. If you prefer a human touch, message us on WhatsApp and a Compoden engineer will help within hours.
Can I use this kit for a school or college project?
Absolutely. The mesh chat network aligns with CBSE practicals, engineering mini-projects, and hackathon IoT challenges. It demonstrates real-world mesh topology and embedded programming.
Do I need soldering?
No soldering at all. Everything connects via breadboards and jumper wires, and the ESP32 boards are powered by Micro USB, making the entire build tool-free.
How do I power the three ESP32 boards?
Each board is powered separately using the included Micro USB cables. Plug them into any standard USB adapter or a multi‑port charger; a single power bank with multiple outputs also works perfectly.
Three ESP32 boards form a self-healing WiFi mesh. Text messages typed on one appear on all OLED screens.
