The ESP32-WROOM-32 38-Pin Development Board (NodeMCU-32S layout) is a high-performance, cost-effective development system designed for modern wireless and embedded systems. Powered by the official ESP32-D0WDQ6 / ESP32-D0WD-V3 system-on-chip, it delivers up to 600 DMIPS of processing horsepower alongside hardware-level security, low power management, and extensive peripheral expansion.

Featuring an onboard USB-to-Serial converter (CP2102 / CH340) and Micro-USB/Type-C interface, the board allows seamless plug-and-play code uploading directly from the Arduino IDE, ESP-IDF, MicroPython, or PlatformIO. The 38-pin expansion format breaks out every usable GPIO pin, offering dedicated channels for capacitive touch, 12-bit ADC inputs, DAC outputs, I2C, SPI, PWM, and hardware UARTs.
