Introduction

The ESP32-WROVER-B combines dual-core processing, WiFi 150Mbps, and Bluetooth 4.2 in a single FCC/CE-certified module. With 4MB Flash and 64Mbit PSRAM, it handles advanced applications like voice recognition and real-time sensor networks without external memory.


Dual-Core Performance for Demanding Tasks

Adjustable 80-240MHz clock speed enables parallel processing of WiFi data streaming and BLE beacon detection without lag.


Expanded Memory for Complex Applications

4MB SPI Flash + 64Mbit PSRAM supports MP3 decoding and high-speed data logging, eliminating crashes in memory-intensive projects.


Ultra-Low Power for Battery-Powered Devices

5µA deep sleep mode extends operational life by 3× compared to ESP8266, ideal for wearables and remote sensors.


Plug-and-Play Wireless Connectivity

Pre-certified PCB antenna (20dBm output) ensures stable 150Mbps WiFi range without RF design expertise.
