    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 analogue 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. 2.1 WiFi. 1 WiFi • 802.11 b / g / n / e / i • 802.11 n (2.4 GHz) at speeds up to 150 Mbps • 802.11 e: QoS mechanism to implement wireless multimedia technology • WMM-PS, UAPSD • A-MPDU and A-MSDU frame aggregation techniques • Block reply • Fragmentation and reorganization • Beacon automatic monitoring / scanning • 802.11
