The core processor ESP32 provides a complete 802.11 b/g/n/e/i wireless local area network (WLAN) and Bluetooth 4.2 solution with minimal physical size. Designed for low-power and mobile consumer electronics, wearable and IoT devices, this chip integrates all the features of WLAN and Bluetooth on-chip, with low cost and good layout. ESP32 also provides an open platform that allows users to flexibly customize functions for different application scenarios.

The ESP32 is a WiFi and Bluetooth system-on-chip (SoC) with industry-leading RF performance, low power consumption and high integration. 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 circuits. The self-calibration circuit implements dynamic auto-tuning to eliminate defects in external circuitry. The ESP32 features two 32-bit, LX6 CPUs with a clock speed of up to 240MHz and a 7-stage pipeline architecture. The ESP32 also integrates a rich analog sensing and digital interface. The ESP32's ultra-low-power RF architecture and patented power-saving technology extend battery life in real-world applications.

The ESP32 is fully compliant with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards, integrates WiFi/Bluetooth/BLE radio and low power technology, and supports an open real-time operating system RTOS. The adjustment cache integrated in ESP32 helps improve system performance and optimize system storage. The flexible RAM/ROM partitioning architecture allows the user to customize to meet specific requirements and usage. The ESP32 can be used as a standalone application or as a slave to the host MCU. As a slave, the ESP32 provides WiFi and Bluetooth capabilities via an SPI/SDIO or I2C/UART interface.

Universal WiFi-BT-BLE MCU module, PCB antenna or ipex antenna, powerful, versatile, easy to use.
