Create an ESP32 Captive Portal for Simple WiFi Provisioning – Complete 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.

Stop hardcoding WiFi credentials and reflashing every time you move your IoT device to a new network. This kit transforms an ESP32 into a self-configuring access point: it broadcasts its own WiFi network, serves a captive portal web page to capture SSID and password, and stores them permanently in EEPROM. The next time it boots, it connects automatically using the saved credentials, with LED indicators and OLED readout showing the status.

What You'll Build

You'll assemble a complete WiFi provisioning module around an ESP32. Power it up, connect your phone to the "ESP32-Setup" network, and a web page opens automatically where you enter your home WiFi details. The device then reboots, connects to that network, and displays the assigned IP address on the 0.96‑inch OLED. A tactile button lets you clear saved credentials to re-enter setup mode – all fully documented and ready to embed into any project.

What You'll Learn

• Create a dual‑mode WiFi access point and station on ESP32 with the Arduino framework
• Implement a captive portal using HTML served by ESPAsyncWebServer
• Save and retrieve credentials from EEPROM for non‑volatile storage
• Integrate an OLED display using I²C to show connection status and IP address

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate project kit is a perfect fit for CBSE Class 11–12 students diving into IoT, B.Tech ECE/EEE undergraduates building prototypes for Smart India Hackathon, and ATL Tinkering Lab facilitators who want a reusable WiFi configuration pattern. If you have basic Arduino experience and want to create commercial-like onboarding experiences for your own devices, this is the project that bridges the gap.

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.
