Key Features
- Dual-Core Processing: Two Xtensa LX6 cores running at up to 240 MHz deliver exceptional performance for multitasking - run Wi-Fi communication on one core while processing sensor data on the other.
- Built-in Wi-Fi & Bluetooth: Integrated 802.11 b/g/n Wi-Fi and Bluetooth 4.2 (BLE + Classic) eliminate the need for external wireless modules, reducing cost and complexity.
- 38-Pin Expanded Layout: More GPIO pins than the standard 30-pin variant, giving you access to additional ADC channels, touch sensors, and communication interfaces for complex projects.
- Rich Peripheral Set: 18 ADC channels, 2 DAC outputs, 10 capacitive touch pins, SPI, I2C, I2S, UART, CAN bus, and PWM on virtually every GPIO - one board handles almost any sensor or actuator.
- Ultra-Low Power Modes: Deep sleep current as low as 10 uA makes the ESP32 ideal for battery-powered IoT devices, remote sensors, and wearable projects.
- Breadboard-Friendly Design: Standard 2.54 mm pin headers allow direct mounting on breadboards for rapid prototyping without soldering.
- Multi-Platform Support: Program using Arduino IDE, Espressif's ESP-IDF, MicroPython, or PlatformIO - choose the environment that suits your skill level and project requirements.
- On-Board USB-to-Serial: Integrated CP2102 or CH340 chip enables plug-and-play programming and serial debugging via micro-USB cable.
- Built-in Boot & Reset Buttons: Dedicated BOOT and EN (reset) buttons simplify firmware flashing and board reset during development.
- On-Board LED: Built-in user-programmable LED connected to GPIO2 for quick testing and status indication.
Why Choose the ESP32 38-Pin NodeMCU?
- 100% Authentic: Sourced directly from trusted suppliers and authorized distributors - no clones or counterfeit chips.
- More Pins, More Possibilities: The 38-pin variant exposes additional GPIOs compared to the 30-pin version, giving you the flexibility needed for pin-intensive projects.
- All-in-One Wireless Solution: Wi-Fi + Bluetooth on a single chip means fewer components, lower cost, and a cleaner design for IoT applications.
- Massive Community & Resources: Thousands of tutorials, libraries, and open-source projects available online - you'll never be stuck without a solution.
- 1-5 days shipping: Fast delivery from our Bengaluru warehouse to most locations across India. Same-day delivery available in Bengaluru.
