Omschrijving

ESP32-WROVER-B combines 2.4 GHz Wi-Fi and dual-mode (Classic and Low-Energy) Bluetooth. Such a combination ensures unparalleled connectivity in different application scenarios. Wi-Fi enables internet connectivity over a large area, while Classic Bluetooth allows users to securely connect ESP32-WROVER-B to their mobile phones for exchanging data over short distances by using short-wavelength UHF radio waves. Additionally, ESP32-WROVER-B can function as a beacon, broadcasting its identifier via Bluetooth Low Energy to portable electronic devices within a maximum radius of 50 meters.

The new module is built around ESP32-D0WD instead of ESP32-D0WDQ6. ESP32-D0WD has two CPU cores that can be individually controlled, while its CPU clock frequency is adjustable, ranging from 80 MHz to 240 MHz. It integrates a variety of peripherals, including capacitive touch sensors, a Hall sensor, an SD card interface, an Ethernet port, high-speed SPI, UART, I2S and I2C. Users can power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for any changes or threshold crossings.

The operating system of all chips in the ESP32 series is FreeRTOS with a light-weight Internet Protocol (LwIP). A Transport Layer Security (TLS 1.2) with hardware acceleration is built-in as well. Secure (encrypted) over-the-air (OTA) upgrade is supported, allowing developers to upgrade their products, even after the initial release of the latter, with little effort at minimal cost.
