Description: ESP32-WROVER-E and ESP32-WROVER-IE are two powerful generic WiFi BT-BLE MCU modules that target a wide range of applications, from low-power sensor networks to demanding tasks such as voice coding, music streaming and MP3 decoding. ESP32-WROVER-E is supplied with a PCB antenna and ESP32-WROVER-IE with an IPEX antenna. Both have a 4 MB external SPI flash and an additional 8 MB SPI Pseudo Static RAM (PSRAM).The core of the module is the ESP32-D0WD-V3 chip*. The embedded chip is designed to be scalable and adaptable. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a power-saving co-processor that can be used instead of the CPU to conserve power and perform tasks that do not require much processing power, such as monitoring peripherals. ESP32 integrates a variety of peripheral devices, such as capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S, AND I²C. The integration of Bluetooth®, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted and the module is versatile: The use of Wi-Fi allows for a wide physical range and a direct connection to the Internet via a Wi-Fi router, while the use of Bluetooth allows a convenient connection to the phone or the sending of low energy beacons for detection. The quiescent current of the ESP32 chip is less than 5 µA, making it suitable for battery-powered and portable electronics applications. The module supports a data rate of up to 150 Mbps and 20 dBm output power at the antenna to ensure the widest possible physical range. This provides industry-leading specifications and performance for electronic integration, range, power consumption, and connectivity. The operating system selected for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is also installed. A secure (encrypted) over-the-air upgrade (OTA) is also supported, so that users can update their products with minimal effort after they have been released.
