Ai-Thinker NodeMCU-32S ESP32 Dev Board (IPEX) – Wi-Fi BLE
Ai-Thinker NodeMCU-32S ESP32 Development Board (IPEX Version)
The NodeMCU-32S by Ai-Thinker is an ESP32-based development board with an IPEX antenna connector for external antenna support, offering improved range and signal quality over PCB antenna variants. It integrates Wi-Fi 802.11 b/g/n and Bluetooth 4.2/BLE on a breadboard-friendly module with USB-to-serial programming. Designed for IoT and wireless prototyping, this board delivers dual-core processing at up to 240 MHz, 4MB flash, and extensive GPIO for sensor and actuator projects.

Compatibility
Fully compatible with Arduino IDE and MicroPython firmware. The board works with any 3.3V-level I2C, SPI, or UART peripherals. It pairs easily with common sensors like DHT22, BME280, or ultrasonic modules. The on-board USB-to-serial (CP2102) allows direct programming from any computer.
Wiring Notes
Power the board via micro-USB (5V) or apply 5–12V to the Vin pin (onboard regulator provides 3.3V). All GPIOs operate at 3.3V—do not exceed this level to avoid damage. The EN pin is pulled high; connect to GND to reset. For the IPEX connector, attach an appropriate 2.4 GHz external antenna for extended range.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino IDE?
Yes, install the ESP32 board package via Boards Manager, then select "NodeMCU-32S" as the board. No extra configuration needed.
Do I need an external antenna for this IPEX version?
An external antenna is recommended for better range, but the board has a small on-board ceramic antenna that works without one for short-range prototyping.
Can I power it with a 9V battery?
Yes, connect a 9V battery to the Vin pin (accepts 5–12V). The onboard regulator provides the necessary 3.3V for the ESP32.
