Overview
Description
ESP32-WROVER-IB is Espressif’s high‑memory variant of the ESP32-WROVER family. It combines an Xtensa LX6 MCU with 2.4 GHz Wi‑Fi and Bluetooth (Classic + LE) in a compact module. The IB variant ships with onboard flash and external PSRAM, enabling larger programs and RAM‑hungry tasks. It provides a rich peripheral set (SPI, I2C, I2S, UART, PWM, ADC/DAC, CAN, etc.) and hardware crypto, plus multiple power modes for low‑power IoT apps. The module runs from 3.3V and is designed for easy PCB integration via castellated pads. Development is supported by ESP-IDF, Arduino core, and other toolchains. Typical use: IoT sensors, audio, wearables, gateways, and edge devices requiring Wi‑Fi/Bluetooth and memory headroom.
Features
Here are the core features of ESP32-WROVER-IB (module in the ESP32-WROVER family):
- Dual-core 32-bit Xtensa LX6 CPU, up to 240 MHz
- 2.4 GHz Wi‑Fi (802.11 b/g/n) plus Bluetooth Classic and BLE
- External SPI flash and PSRAM (capacities vary by module)
- Rich I/O and peripherals: UARTs, SPI, I2C, I2S, PWM, ADC (12‑bit SAR, multiple channels), DACs, CAN, IR
- Hardware security: crypto engine (AES, SHA-2, RNG), Secure Boot and Flash Encryption
- RTC and ultra-low-power deep-sleep modes for power efficiency
- On-module RAM/ROM and full ESP-IDF ecosystem support
- Industrial-grade IB variants available with extended temperature and robustness (check datasheet for exact range)
Note: exact flash/PSRAM sizes and temperature specs vary by specific module revision; consult the datasheet for precise numbers.
