    ESP32 function block diagram

    • ESP32 is a WiFi and Bluetooth system-on-chip (SoC) with industry-leading RF performance, low power and high integration advantages. The ESP32 integrates complete transmit / receive RF functions including antenna switches, RF balun, power amplifiers, low noise amplifiers, filters, power management modules and advanced self-calibration circuitry. The self-calibration circuit implements dynamic auto-tuning to eliminate defects in external circuitry. ESP32 with two 32-bit, LX6 CPU, clocked at up to 240MHz, using 7-level pipeline architecture. ESP32 also integrates a wealth of analog sensing and digital interface.

    • ESP32's ultra-low-power RF architecture and patented power-saving technology extend the battery life of practical applications.

    • ESP32 fully complies with WiFi 802.11b / g / n / e / i and Bluetooth 4.2 standards, integrated WiFi / Bluetooth / BLE RF and low power technology, and supports open real-time operating system RTOS. ESP32's integrated tuning cache helps improve system performance and optimize system storage. The flexible RAM / ROM partition architecture allows users to customize to meet specific requirements and usage.

    • ESP32 can be used as a standalone application or as a slave for a host MCU. As a slave, the ESP32 provides WiFi and Bluetooth via the SPI / SDIO or I2C / UART interface.
