Overview

The ESP32-MINI-1-H4 is a compact, dual-core Wi-Fi and Bluetooth module powered by the Xtensa 32-bit LX6 microprocessor. It integrates 4MB of flash memory and provides a high-density footprint of 13.2mm by 19.0mm with 55 pins for comprehensive peripheral access. This module supports concurrent 802.11 b/g/n Wi-Fi and Bluetooth v4.2 +EDR/BLE connectivity for complex IoT communication requirements.

Why Choose This Part

The module offers a 240MHz clock speed and 18 ADC channels in a highly integrated package, reducing PCB complexity. Its low sleep current of 50uA and flexible power management make it suitable for battery-operated devices requiring high burst performance.

Applications

Industrial Gateways
Utilizes dual-core processing and diverse interfaces like TWAI (CAN) and Ethernet to bridge local sensor networks to the cloud.
Smart Home Appliances
Enables remote control and monitoring via Wi-Fi with local low-latency interaction through Bluetooth LE.
Motor Control & Robotics
Leverages dedicated motor PWM channels and pulse counters for precise motion control in compact wireless systems.
Audio Streaming
Uses I2S and high-speed processing for wireless audio applications including CVSD and SBC codec support.

Getting Started

Develop using the Espressif IoT Development Framework (ESP-IDF) or the Arduino IDE with the ESP32 core. Hardware prototyping is best achieved using the ESP32-DevKitM-1 evaluation board, which accommodates the MINI series footprint. Calibration and flashing are performed via UART using the esptool.py utility.
