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. 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 i security features: pre-authentication and TSN • Supports WPA / WPA2 / WPA2-Enterprise / WPS encryption • Infrastructure BSS Station mode / SoftAP mode • Wi-Fi Direct (P2P), P2P discovery, P2P GO mode, and P2P power management • UMA compatible and certified • Antenna diversity and selection 2.2 Bluetooth 2 Bluetooth • Bluetooth v4.2 complete standard, including traditional Bluetooth (BR / EDR) and low power Bluetooth (BLE) • Supports standard Class-1, Class-2 and Class-3, and eliminates the need for external power amplifiers • Enhanced precision power control • Output power up to + 10 dBm • The NZIF receiver has BLE receive sensitivity of -98 dBm • Adaptive Frequency Hopping (AFH) • Standard HCI based on SDIO / SPI / UART interface • High-speed UART HCI with speeds up to 4 Mbps • Supports BT 4.2 controller and host protocol stack • Service Discovery Protocol (SDP) • Universal Access Application (GAP) • Security Management Protocol (SMP) • Low power Bluetooth • ATT / GATT • HID • Supports all GATT-based low-power Bluetooth applications • SPP-Like Low Power Bluetooth Data Transparency Protocol • BLE Beacon • A2DP / AVRCP / SPP, HSP / HFP, RFCOMM • CVSD and SBC audio codec algorithms • Bluetooth piconet and Scatternet 2.3 CPU and storage • Xtensa® 32-bit LX6 dual-core processor with computing power up to 600 DMIPS • 448 KByte ROM •
