| Processor | Tensilica L106 |
The NodeMCU v3 remains one of the most popular Wi-Fi development boards in India — and for good reason. At ₹179, it gives you a full TCP/IP stack, 11 GPIO pins, and Arduino IDE compatibility in a breadboard-friendly form factor.
If your project only needs Wi-Fi (no Bluetooth), is power-constrained, or you are building in quantity on a tight budget, the NodeMCU v3 is the right call. It draws less current in deep sleep than the ESP32 and costs ₹70 less per unit — meaningful at scale.
Wi-Fi weather stations, MQTT sensor nodes, basic home automation triggers, web server on chip, simple IoT data loggers. Works well with DHT11 or DHT22 sensors for temperature/humidity monitoring over Wi-Fi.
