ESP32-WROVER Schematic Circuit Diagram
A step upgrade of ESP-WROOM-32 described above with an additional 4 MB SPI PSRAM (Pseudo static RAM). Module is provided in two versions: ‘ESP32-WROVER’ with PCB antenna (shown below) and ‘ESP32-WROVER-I’ with an IPEX antenna.
ESP32-WROVER 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 task, such as voice encoding, music streaming, and MP3 decoding.
At the core of this module is the ESP32-DOWDQ6 chip same as the ESP-WROM-32 module.
The chip embedded is designed to be scaled and adaptive. There are two CPU cores that can be individually controlled 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 co-processor to constantly monitor the peripherals for changing or crossing of thresholds.
The integration of Bluetooth, Bluetooth, and WiFi ensure that a wide range of applications can be targeted and the module is future-proof: using WiFi allows a large physical range and direct connection to the internet.
