ESP32-WROVER-B 8M 64Mbit Wi-Fi Bluetooth Module

The Espressif ESP32-WROVER-B Wireless Module is a powerful, general WiFi-BT-BLE MCU module targeting a wide range of applications. These applications range from low-power sensor networks to the most demanding tasks such as audio encoding, music streaming and MP3 decoding. ESP32-WROVER-B features 8MB external SPI flash and an additional 64MB SPI Pseudo static RAM (PSRAM).

ESP32-WROVER-B MCU Modules are essentially ESP32-D0WD uses the chip. This SoC has two CPU cores that can be controlled individually, and the CPU clock frequency can be adjusted between 80MHz and 240MHz. ESP32 integrates a rich set of peripherals consisting of capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C.

ESP The -32S Wifi Bluetooth combo module provides SDK Firmware for fast online programming and open source toolchains based on GCC for development support. General low-power IoT sensor hub for manufacturers, hardware engineers, software engineers and solution providers designed for recorders, video streaming for camera, Wi-Fi and Bluetooth enabled devices, Home automation and mesh networking applications.

ESP32 is a single 2.4GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra-low power 40nm technology. Designed and optimized for best power performance, RF performance, ruggedness, versatility, features and reliability for a wide range of applications and different power profiles.

ESP32 less than 10 With external component, it is the most integrated solution for Wi-Fi + Bluetooth applications in the industry. ESP32 integrates antenna switch, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. Therefore, the entire solution occupies a minimal Printed Circuit Board (PCB) area.

ESP32 is designed for mobile, wearable electronics and Internet of Things (IoT) applications. It has many features of state-of-the-art low-power chips, including fine-resolution clock gating, power modes, and dynamic power scaling.
