Build a Custom OTA Update System with Rollback and LED Status

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 deploying firmware updates wirelessly without ever connecting a USB cable, and having a safety net that rolls back automatically if an update fails. This kit gives you exactly that understanding, using a real ESP32 that controls three LEDs to visually signal OTA success, failure, and rollback. You'll move beyond basic Arduino sketches into professional embedded practices-scripting partition layouts, managing non-volatile storage, and living with a production-ready OTA workflow.

What You'll Build

You'll craft a robust ESP32 firmware that features multiple partitions-a factory app, two OTA slots, an NVS area for credentials, and a SPIFFS section for logs and assets. Three LEDs on the breadboard become your dashboard: green lights on successful update, red indicates a failed boot that triggers rollback, and yellow flashes during the OTA process. The physical feedback makes abstract partition concepts tangible.

What You'll Learn

• Design custom partition tables for ESP32 using ESP-IDF tools
• Implement Over-The-Air (OTA) updates with automatic rollback on failure
• Use Non-Volatile Storage (NVS) to preserve Wi-Fi credentials and settings across firmware changes
• Store runtime logs and assets in the SPIFFS flash filesystem
