ESP32 is a powerful WiFi+BLE MCU module that covers a wide range of applications. This ranges from a low-power sensor network to very demanding tasks such as voice encoding, music streaming and MP3 decoding. At the heart of the module is the ESP32-D0WDQ6* chip, designed to be adaptable and adaptable. It has two CPU cores that can be controlled individually. The clock frequency is adjustable between 80 MHz and 240 MHz. You can also turn off the CPU and use the low-power co-processor to continuously monitor the edge if limit values are changed or exceeded. ESP32 integrates a wide range of devices such as capacitive touch sensors, Hall sensors, low noise amplifiers, SD card interface, Ethernet, high-speed SDIO/SPI, UART, I2S and I2C. The integration of Bluetooth, Bluetooth LE and WiFi makes it possible to use a wide range of applications and make the module suitable for the future: while WiFi has a great physical range and the possibility of connecting to the Internet via a WiFi router, Bluetooth offers the user an easy connection to the smartphone or sending low-power sensors for detection. The ESP 32 chip's standby power consumption is less than 5µA, making it ideal for use with battery-powered or portable electronics. The ESP-Wroom-32 supports data rates of up to 150 Mbps and a PA output power of 20dBm.
