About this product
The ESP32 DevKit V1 is what most IoT projects in India are built on, and for good reason. A dual-core 240 MHz processor, WiFi and Bluetooth on the same chip, 25 usable GPIO pins and capacitive touch inputs, all for less than the price of a school textbook.
Program it from the same Arduino IDE students already know, or switch to MicroPython for a gentler start. It talks to Blynk, Firebase, ThingSpeak and MQTT brokers out of the box, so a sensor reading on a classroom desk can appear on a phone in seconds - which is usually the moment IoT stops being an abstract word.
Typical builds: WiFi-controlled robot cars, smart plant watering systems, air-quality monitors, attendance loggers and Bluetooth gamepads. The 30-pin layout is the widely used one, so it fits the common ESP32 expansion boards and breadboards.
