espressif systems ESP32-WROOM-32 Wi-Fi+BT+BLE MCU module based on Dual Core ESP32-D0WDQ6 chip

详情

1. Overview

ESP**-WROOM**2 is a powerful, generic Wi-Fi+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 ESP**-D0WDQ6 chip*. The chip embedded is designed to be scalable and
adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable
from *0 MHz to **0 MHz. The user may also power off the CPU and make use of the low-power co-processor to
constantly monitor the peripherals for changes or crossing of thresholds. ESP*2 integrates a rich set of peripherals,
ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S and
I²C.
Note:
* For details on the part numbers of the ESP*2 family of chips, please refer to the document ESP*2 Datasheet.
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 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 ESP*2 chip is less than 5 A, making it suitable
for battery powered and wearable electronics applications. The module supports a data rate of up to **0 Mbps,
and *0 dBm output power at the antenna to ensure the widest physical range. As such the module does offer
industry-leading specifications and the best performance for electronic integration, range, power consumption,
and connectivity.
The operating system chosen for ESP*2 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 users can upgrade their products
even after their release, at minimum cost and effort.
