ESP32-WROOM-32 Function Block Diagram

ESP32-WROOM-32 is a WiFi and Bluetooth system level chip (SoC) with industry-leading RF performance, low power consumption, and highly integrated advantages. ESP32-WROOM-32 integrates complete nsmit/receive RF functions, including switches, RF baluns, power amplifiers, low-noise amplifiers, filters, power management modules, and advanced s calibration circuits. The s calibration circuit achieves dynamic automatic adjustment to eliminate defects in external circuits. ESP32-WROOM-32 comes with 2 32-bit, LX6 CPUs, with a main frequency of up to 240MHz, and adopts a 7-stage line architecture. ESP32-WROOM-32 also integrates rich og sensing and dial interfaces.

The ul-low power RF architecture and patented power-saving technology of ESP32-WROOM-32 extend the battery life in practical applications.

ESP32-WROOM-32 fully complies with the standards of WiFi 802.11b/g/n/e/i and Bluetooth 4.2, integrates WiFi/Bluetooth/BLE RF and low-power technology, and supports an open real-time operating system RTOS. The tuning cache integrated with ESP32-WROOM-32 helps improve system performance and optimize system storage. The flexible RAM/ROM partitioning architecture allows users to customize to meet special requirements and usage situations.

ESP32-WROOM-32 can be used as a standalone application or as a device for the host MCU. As a device, ESP32-WROOM-32 provides WiFi and Bluetooth functionality through /SDIO or I2C/UART interfaces.
