ESP32-WROVER-B WiFi/BLE Module with 8MB PSRAM (IPEX antenna)

ESP32‑WROVER‑B WiFi + Bluetooth Module (IPEX Antenna) is a high‑performance wireless MCU module designed for advanced IoT and embedded connectivity applications. Built around the ESP32 dual‑core processor, this WiFi and Bluetooth communication module integrates 4MB SPI Flash and 8MB SPI PSRAM for memory‑intensive edge computing tasks. Dual‑mode wireless connectivity enables both long‑range network communication and low‑power device interaction. With rich peripheral interfaces and a compact surface‑mount footprint, this wireless microcontroller module simplifies integration into smart devices, robotics systems, industrial monitoring nodes, and connected consumer electronics.

Dual‑Core Wireless Processing Architecture

This IoT communication module uses the ESP32‑D0WD chipset featuring two independently controlled CPU cores running between 80 MHz and 240 MHz. Flexible clock control enables performance tuning or power optimization depending on application needs. A low‑power co‑processor allows continuous peripheral monitoring while the main cores remain powered down, enabling efficient event‑driven operation. Combined WiFi and Bluetooth connectivity expands communication options for mobile devices, routers, and distributed sensing nodes across a wide range of embedded networking scenarios.

Rich Peripheral Integration for Embedded Systems

This wireless MCU board integrates an extensive set of peripherals supporting complex embedded designs without external controllers. Supported interfaces include SD card, UART, SPI, I2C, I2S, ADC, DAC, PWM outputs, infrared communication, pulse counters, and capacitive touch sensors. Built‑in Hall sensing and GPIO expansion provide additional hardware interaction capabilities. Such extensive peripheral support allows rapid development of connected controllers, data acquisition systems, and intelligent edge devices.

High‑Performance Wireless Connectivity

The compact wireless communication unit integrates 2.4GHz WiFi alongside Bluetooth v4.2 BR/EDR and BLE, allowing both high‑bandwidth internet connectivity and low‑energy device pairing. WiFi enables direct network access through routers while Bluetooth supports smartphone interaction and beacon broadcasting. Data transmission rates up to 150 Mbps and up to 20 dBm antenna output power enable long communication ranges. Ultra‑low sleep current below 5 µA supports battery‑powered designs such as wearable electronics and remote IoT sensor nodes.

Secure Embedded Software Ecosystem

This embedded connectivity module operates with FreeRTOS and the LwIP networking stack, providing a robust real‑time software environment for connected devices. Built‑in TLS 1.2 hardware acceleration enhances secure communication for cloud and network applications. Secure encrypted over‑the‑air firmware updates allow product maintenance and feature upgrades after deployment, making the wireless MCU module suitable for long‑life smart hardware products and scalable IoT deployments.
