The ESP32-WROOM-32E-N4 is a powerful, generic Wi-Fi + BT + BLE MCU module designed for a wide variety of applications, ranging from low-power sensor networks to demanding tasks such as voice encoding, music streaming, and MP3 decoding. It is based on the ESP32-D0WD-V3 SoC, featuring two individually controllable CPU cores with an adjustable clock frequency from 80 MHz to 240 MHz. The module integrates 4MB of external SPI flash and supports an operating temperature range of -40°C to 85°C. It includes an on-board PCB antenna and a rich set of peripherals including touch sensors, Hall sensors, and high-speed SPI/UART/I2C interfaces.
