About this item

ESP32-WROOM-32E N4 is a powerful Wi-Fi + Bluetooth + BLE MCU module from Espressif, designed for a wide range of applications — from low-power IoT sensor networks to more advanced embedded tasks. This N4 variant includes 4MB Flash and comes with a reliable PCB antenna for stable wireless performance.

At its core, the module features the ESP32-D0WD-V3 chip, built to be scalable and adaptive. It includes dual CPU cores that can be controlled independently, with an adjustable clock speed from 80 MHz to 240 MHz to match various performance needs.

The chip also includes an ultra-low-power coprocessor that handles simple background tasks, such as peripheral monitoring, without waking the main CPUs — making it ideal for energy-efficient IoT applications.

The ESP32 integrates a rich set of peripherals, including capacitive touch sensors, Hall sensor, SD card interface, Ethernet support, high-speed SPI, UART, I2S, and I2C, offering excellent flexibility for embedded and IoT development.
