概述

Description

ESP32-WROVER-IB is Espressif’s ESP32-WROVER family module, a dual‑core LX6 MCU with built‑in 2.4 GHz Wi‑Fi and Bluetooth (classic/BLE) and added external PSRAM. It’s designed for memory‑heavy IoT/edge apps where standard WROOM variants may fall short.
Key points:
- CPU and connectivity: dual‑core Xtensa LX6 up to ~240 MHz; Wi‑Fi 802.11 b/g/n and Bluetooth Classic/BLE.
- Memory: external PSRAM on the module (plus onboard flash). Memory size varies by variant.
- Peripherals: wide GPIO, UART/SPI/I2C/I2S, PWM, ADC/DAC, touch sensors, SDIO, etc.
- Power/voltage: operates at 3.3V logic; low‑power modes available.
- Software support: ESP-IDF, Arduino core, MicroPython, etc.
- Use cases: memory‑intensive IoT, audio/data buffering, image/video processing, edge AI, sensors, gateways.
- Variant note: IB is a specific revision/temperature/antenna option; check the datasheet for exact memory, antenna type, and operating range.
In short: a high‑RAM ESP32 module for demanding IoT/edge applications.

Features

Key features of ESP32-WROVER-IB (ESP32-WROVER family):
- Dual-core Xtensa LX6 CPU up to 240 MHz
- 520 KB internal SRAM + external PSRAM (typical up to 8 MB); external SPI flash (configurable sizes, usually 4–16 MB)
- 2.4 GHz Wi‑Fi (802.11 b/g/n) and Bluetooth BR/EDR + BLE
- Rich I/O and peripherals: GPIOs, SPI, I2C, I2S, UART, CAN, PWM, ADC (12‑bit), DAC, touch sensors, SDIO/SD card
- Ultra-low-power with ULP co-processor and multiple sleep modes
- Hardware crypto accelerators (AES, SHA, RSA, ECC) and RNG; secure boot and flash encryption
- OTA updates and multi-boot/partition support
- Broad development support: ESP-IDF and Arduino cores; JTAG debugging; strong ecosystem
- Module integrates RF front-end and antenna; compact form factor
Note: exact RAM/PSRAM/flash sizes vary by module variant; the WROVER family commonly uses external flash and PSRAM options.

Package

The ESP32-WROVER-IB is a metal-shielded surface-mount (SMT) castellated PCB RF module — a ready-to-solder, shielded Wi-Fi/Bluetooth module.

Pinout

ESP32‑WROVER‑IB is a 38‑pin surface‑mount module. Key pin functions (per datasheet):
- Power/ground: 3.3V VCC, multiple GND pins, EN/CHIP_EN (reset/enable), IO0 (boot mode).
- UART: TX0/RX0 (GPIO1/GPIO3) and other UARTs on generic GPIOs.
- SPI/I2S/SDIO: SPI0/1, I2S and SDMMC interfaces for peripherals and storage.
- PSRAM/Flash interface: dedicated pins for external PSRAM and flash (GPIO6–GPIO11 used internally; not for general I/O).
- GPIO: many multifunctional GPIOs supporting PWM (LEDC), ADC (12‑bit ADC1 & ADC2), two DAC channels, touch sensors (T0–T9), RTC GPIOs.
- Other: I2C (via GPIOs), CAN, Ethernet MAC (RMII signals available on pins), JTAG (MTDI/MTCK/MTMS/MTDO).
For exact pin numbering, electrical characteristics and reserved pins (notably GPIO6–11), consult the official Espressif ESP32‑WROVER datasheet and module pinout diagram.
