The ESP-WROVER-32IB is an exceptional module that combines Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) making it ideal for a variety of applications. This device offers industry-leading specifications and reliable performance with an external U.FL (IPEX) connector and 8MB Pseudo Static RAM (PSRAM).
Supported by the ESP32-D0WD chip, the module utilizes the freeRTOS operating system with LwIP and a built-in TLS 1.2 with hardware acceleration. The WROVER-32 is an open-source module allowing the user to customize as needed. GitHub. provides a large collection of example code and information for device customizations.
With the secure encrypted over-the-air (OTA) system, updates are made remotely with minimal cost and effort.
The module provides two (2) individually controlled CPU cores with adjustable clock frequency of 80 MHz to 240 MHz. The CPU can be powered off while a separate low power co-processor constantly monitors the peripherals for changes in status.
Peripherals included in the ESP32-D0WD chip are:
