ESP32-WROOM-32D & ESP32-WROOM-32U generic Wi-Fi+BT+BLE MCU modules Datasheet
■ESP32-WROOM-32D and ESP32-WROOM-32U are powerful, generic Wi-Fi+BT+BLE MCU modules that target 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
■ESP32-WROOM-32U is different from ESP32-WROOM-32D in that ESP32-WROOM-32U integrates a U.FL connector. For detailed information of the U.FL connector please see Chapter10. Note that the information in this data sheet is applicable to both modules. Any differences between them will be clearly specified in the course of this document. Table1lists the difference between ESP32-WROOM-32D and ESP32-WROOM-32U
■At the core of the two modules is the ESP32-D0WD chip that belongs to the ESP32 series* of chips. 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 80 MHz to 240 MHz. The chip also has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring of peripherals. ESP32 integrates a rich set of peripherals, ranging fro mcapacitive touch sensors, Hall sensors, 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 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 ESP32 chip is less than 5μA, making it suitable for 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 offer industry-leading specifications and the best performance for electronic integration, range, power consumption,and connectivity.
■The operating system chosen for ESP32 is free RTOS with LwIP; TLS 1.2 with hardware acceleration is built in a swell. Secure (encrypted) over the air (OTA) upgrade is also supported, so that users can upgrade their product seven after their release, at minimum cost and effort
