ESP32 Captive Portal Configuration Kit: Create IoT Devices That Configure WiFi Without Hardcoding Credentials

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 device that you can deploy anywhere—the user simply connects to its WiFi hotspot, enters a home network password via a browser, and the device connects automatically, no code changes needed. With this kit, you’ll build exactly that: an ESP32 gadget that spawns an access point at first boot, serves a responsive web portal, and stores credentials permanently in EEPROM. This is the same captive portal technique used by commercial IoT products, and now you can master it hands-on, from soldering-free assembly to live deployment.

What You'll Build

You’ll assemble a compact device with an OLED screen that displays connection status, a tactile button to trigger WiFi reset, and two LEDs for visual feedback. Once ready, power it up, and from your phone you’ll see an “ESP32-Setup” network. After connecting, a browser automatically opens a page where you enter your router’s SSID and password. After saving, the ESP32 reboots, connects to your WiFi, and shows the assigned IP on the OLED—ready for further IoT tasks like data logging, MQTT telemetry, or remote control.

What You'll Learn

• Programming an ESP32 to create a WiFi access point and redirect users to a captive portal using Arduino framework
• Building a responsive HTML/CSS/JS web interface for credential input, served directly from the microcontroller
• Storing and retrieving data from EEPROM so WiFi settings persist across power cycles
• Integrating an OLED display to show real-time connection status, SSID, and IP address on a 0.96-inch screen
