This is ESP WROOM 32 MCU Module. ESP WROOM 32 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 ESP32S chip, which is designed to be scalable and
adaptive. There are 2 CPU cores that can be individually controlled or powered, 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. ESP32S integrates a rich set
of peripherals, ranging from capacitive touch sensors, Hall sensors, low-noise sense
amplifiers, SD card interface, Ethernet, high-speed SDIO/SPI, UART, and I²C.
Using Bluetooth, users can connect to their phone or broadcast low energy beacons for its
detection. The use of Wi-Fi enables a large physical range, as well as a direct connection
to the internet via a Wi-Fi router. Perfect for wearable electronic or battery-powered
applications, the ESP32 chip uses less than 5µA.
In addition, this module can support data rates of up to 150 Mbps and 22 dBm output power at
the PA in order to allow for the widest physical range.
