ESP32 Captive Portal Config Kit – Plug‑and‑Play WiFi Provisioning with OLED Feedback

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 powering up your ESP32, connecting your phone to its own WiFi network, and a browser page automatically opens asking for your home WiFi password. Once you enter, it saves and connects – all without touching a line of hardcoded credentials. This kit turns that concept into a real, working device with visual feedback on an OLED screen and LEDs. It’s the exact provisioning technique used in commercial smart plugs and IoT gadgets.

What You'll Build

A self-contained ESP32 device that boots as an access point, serves a captive portal web page over its own WiFi, captures the WiFi SSID and password entered via a phone or laptop browser, stores them in non-volatile EEPROM, then reboots into station mode and connects to your network. An OLED displays the connection status, while LEDs indicate portal activity and successful connection. You’ll have a ready-to-deploy IoT provisioning module you can integrate into future projects.

What You'll Learn

• Configuring ESP32 as a soft access point and web server simultaneously
• Designing a captive portal using HTML forms and processing HTTP POST requests
• Reading and writing persistent data to EEPROM for credential storage
• Integrating an OLED display and LEDs to provide real‑time user feedback during provisioning

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for intermediate makers who have basic Arduino or ESP32 experience and want to dive into real-world IoT device provisioning. It’s ideal for CBSE Class 11-12 students working on IoT projects, B.Tech ECE/EEE students building prototypes for hackathons like Smart India Hackathon, and ATL Tinkering Lab mentors guiding students on connected devices. If you’ve ever wondered how commercial smart plugs get onto your WiFi without a screen, this kit reveals the exact technique.

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.
