ESP32-WROVER Wifi ve Bluetooth Modülü

     ESP32-WROVER is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications,ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streamingand MP3 decoding.This module is provided in two versions: one with a PCB antenna, the other with an IPEX antenna. ESP32-WROVER features a 4 MB external SPI flash and an additional 8 MB SPI Pseudo static RAM (PSRAM).

     At the core of this module is the ESP32-D0WDQ6 chip*. The chip embedded is designed to be scalable andadaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustablefrom 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power co-processor toconstantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals,ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S andI²C.

     The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted,and that the module is all-around: using Wi-Fi allows a large physical range and direct connection to the Internetthrough a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcastlow energy beacons for its detection. The sleep current of the ESP32 chip is less than 5A, making it suitablefor battery powered and wearable 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 physical range. As such the module does offerindustry-leading specifications and the best performance for electronic integration, range, power consumption,and connectivity.The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in aswell. Secure (encrypted) over the air (OTA) upgrade is also supported, so that users can upgrade their productseven after their release, at minimum cost and effort
