ESP32 NVS Config Storage Kit: Build Persistent Configuration Systems with Web Dashboard

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 an IoT device that can update its own WiFi password or adjust a sensor alert threshold without any reflashing – just by opening a web page. This kit gives you the hardware and guided experience to build exactly that, using the ESP32’s Non-Volatile Storage (NVS) partition. You’ll store credentials and thresholds that survive power cycles, then modify them on the fly through a responsive dashboard served directly from the microcontroller. It’s a foundational technique used in connected home automation, industrial monitoring, and campus-scale projects where configuration must be both durable and remotely editable.

What You'll Build

You’ll assemble an ESP32 circuit that reads two tactile buttons, controls indicator LEDs, and presents configuration values on the OLED. The NVS partition stores the current WiFi SSID, password, and a sensor threshold. When the device boots, it connects automatically; if the WiFi credentials change, you just open the web UI from any browser, type the new values, and they’re permanently saved. The LEDs and OLED provide real-time feedback, making the persistence logic tangible and easy to debug.

What You'll Learn

• Partition and manage the ESP32’s Non-Volatile Storage (NVS) for durable, outage-proof data
• Write code to read and write WiFi credentials and numeric thresholds without losing them after reset
• Serve a captive web interface from the ESP32 that communicates with NVS via HTTP endpoints
• Integrate physical inputs (buttons) and display code to confirm saved configuration changes

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate project is designed for CBSE Class 11–12 students working on IoT-based practicals, B.Tech ECE/EEE first-year students at NIT/IIT/VIT/BITS who need a solid embedded systems lab exercise, and Smart India Hackathon teams building configuration-driven prototypes. It also fits seamlessly into ATL Tinkering Labs where instructors want to showcase persistent storage and web interfaces without jumping between disjointed online tutorials.

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.
