Key Features
- Dual-Core 240 MHz Processor: Run WiFi communication on one core and your application logic on the other - no lag, no compromise on performance.
- Built-in WiFi & Bluetooth: Connect to WiFi networks for IoT cloud communication or use Bluetooth/BLE for short-range device pairing - no external modules needed.
- 38 Accessible GPIO Pins: The wide-pin variant exposes all available GPIOs, giving you maximum I/O for complex multi-sensor and multi-actuator projects.
- Rich Peripheral Set: Includes 18 ADC channels, 2 DAC channels, 10 capacitive touch inputs, SPI, I2C, I2S, UART, CAN bus, and hardware PWM on every GPIO.
- Ultra-Low Power Modes: Deep sleep current as low as 10 uA makes it ideal for battery-powered IoT deployments and remote sensor nodes.
- Multi-Platform Programming: Program using Arduino IDE for quick prototyping, ESP-IDF for production-grade firmware, or MicroPython for rapid scripting.
- Onboard USB-to-Serial Converter: Plug-and-play programming via Micro-USB - no external programmer required.
- Onboard Antenna: PCB trace antenna provides reliable wireless range without external antenna hardware.
- Hall Effect & Temperature Sensors: Built-in sensors on the ESP32 chip for detecting magnetic fields and monitoring chip temperature.
- OTA Update Support: Update firmware wirelessly over WiFi - perfect for deployed devices that can't be physically accessed.
Why Choose the ESP32 38-Pin Board?
- More Pins, More Possibilities: The 38-pin variant exposes GPIOs that the 30-pin version leaves out, including additional ADC, touch, and communication pins - essential for advanced projects.
- All-in-One Connectivity: WiFi + Bluetooth + BLE on a single chip eliminates the need for separate communication modules, reducing cost and complexity.
- Industry-Standard ESP32 Chip: Powered by Espressif's ESP32-WROOM-32 module - trusted by thousands of commercial products and millions of makers worldwide.
- Massive Community & Resources: Thousands of tutorials, libraries, and open-source projects available - you'll never be stuck without a solution.
- 100% Authentic from The Engineer Store: Sourced directly from authorized distributors. No clones, no compromises.
- 1-5 days shipping from Bengaluru: Fast delivery across India with same-day dispatch
