Description

For ultra-low-power operation, the main CPU cores can be powered down while a low-power coprocessor continuously monitors peripherals and system thresholds. This makes the ESP-WROOM-32 ideal for battery-powered and wearable devices, with deep sleep current consumption of less than 5 µA.

The module supports Wi-Fi and Bluetooth (Classic + BLE), enabling high-speed wireless connectivity, internet access via routers, and Bluetooth beacon broadcasting. With data rates up to 150 Mbps and RF output power up to 22 dBm, it offers excellent range and performance.

ESP32 integrates a rich set of peripherals including capacitive touch sensors, Hall sensor, SD card interface, Ethernet, SDIO/SPI, UART, and I²C, making it suitable for a wide range of advanced applications.
