ESP32-WRO0M-32 Function Block Diagram

ESP32-WRO0M-32 is a WiFi and Bluetooth system on chip (SoC) with industry-leading RF performance, low power consumption, and high integration advantages. The ESP32-WR00M-32 integrates complete RF transmission/reception functions, including antenna switches, RF baluns, power amplifiers, low-noise amplifiers, filters, power management modules, and advanced self calibration circuits. The self calibration circuit achieves dynamic automatic adjustment to eliminate defects in external circuits. ESP32-WR00M-32 is equipped with 2 32-bit, LX6 CPUs, with a clock speed of up to 240MHz, and adopts a 7-stage pipeline architecture. ESP32-WR00M-32 also integrates rich analog sensing and digital interfaces.

The ultra-low power RF architecture and patented power-saving technology of ESP32-WRO0M-32 extend the battery life of practical applications.

ESP32-WRO0M-32 fully complies with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards, integrates WiFi/Bluetooth/BLE RF and low-power technology, and supports an open real-time operating system RTOS. The adjustment cache integrated in ESP32-WRO0M-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 scenarios.

ESP32-WRO0M-32 can be used as a standalone application or as a slave device for the host MCU. As a slave device, ESP32-WRO0M-32 provides WiFi and Bluetooth functionality through SPI/SD10 or I2C/UART interfaces.
