ESP32-WROVER 4MB Module with Bluetooth and WiFi (ESP32-WROVER)
 Description:

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 streaming and MP3 decoding. At the core of this module is the ESP32-D0WDQ6 chip*, same as ESP-WROOM-32 module. Compared to ESPWROOM-32, ESP32-WROVER has an additional SPI Pseudo static RAM (PSRAM) of 32 Mbits. As such, ESP32- WROVER features both 4 MB external SPI flash and 4 MB external PSRAM. The ESP32-WROVER module has a PCB antenna, while the ESP32-WROVER-I uses an IPEX antenna. The information in this datasheet is applicable to both of the two modules. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power coprocessor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, low-noise sense amplifiers, 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 that the module is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP32 supports a data rate of up to 150 Mbps, and 22 dBm output power at the antenna to ensure the widest physical range. As such the chip does offer industry-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 as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that developers can continually upgrade their products even after their release.

Package includes:

1 x ESP32-WROVER 4MB Module

    SONOFF® Dual Channel WIFI APP Remote Control Switch Socket Module 250V For Smart Home (C5 Sonoff dual ch switch)

    Sonoff Dual is a WiFi based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means 1 Sonoff Dual control switch equals to 2 Sonoff basic switches! Sonoff Dual 2 gang light switch inherits Sonoff Basic switch’s advantages such as easy installation and operation, quick WiFi access, remote control through APP EweLink.

    In the application eWeLink, available on both iOS and Android, users can independently turn on/off each of the two connected devices. But the button on Sonoff Dual 2 gang WiFi light switch is not an ON/OFF toggle switch, it is only a WiFi pairing button. Users can set single/repeat/countdown timing schedules to turn on/off at a specified time, and also share with others so that they can control together.

    Works With Amazon Alexa

    You can ask Alexa to turn on/off Sonoff Dual.

    Standard voice control commands phrases for Sonoff Dual (if you just say the device name, Alexa will turn on/off all the 2 gangs immediately):

    Alexa, turn on {deviceName}
    Alexa, turn off {deviceName}

    Alexa, turn on {deviceName} {gangName}
    Alexa, turn off {deviceName} {gangName}

    Explanation: if the device name of your Sonoff Dual is "My Switch", the gang name is "Gang 1", then you can control with "Alexa, turn on My Switch Gang 1".
