The ESP32 (ESP-32) Dual-Core Module is the industry-standard “System on a Chip” (SoC) designed for high-performance wireless connectivity. This specific version is fully pin-compatible with the ESP-32S footprint, offering a seamless upgrade path for existing hardware designs in 2025. It integrates a powerful dual-core processor, making it the ideal engine for complex IoT applications that require simultaneous Wi-Fi and Bluetooth communication.
Product Description
The ESP-32 Dual-CPU module is a robust, low-power solution for the modern IoT era. At its core is the Xtensa® Dual-Core 32-bit LX6 microprocessor, which allows users to dedicate one core to wireless protocol management and the second core to application logic. This architecture ensures high-speed processing without the latency often found in single-core modules.
Equipped with integrated Wi-Fi and Dual-Mode Bluetooth (Classic + Low Energy), this module serves as a versatile bridge between legacy devices and the cloud. Its compact SMD footprint is designed for both high-volume industrial manufacturing and rapid prototyping for individual engineers. With extensive built-in security features, it provides a safe and reliable platform for smart home, industrial automation, and edge computing.
Key Features
  • Dual-Core Processing (Double CPU): Two independent cores capable of up to 240 MHz for maximum multitasking efficiency.
  • Hybrid Wireless Connectivity: Integrated 2.4 GHz Wi-Fi (802.11 b/g/n) and Dual-Mode Bluetooth (Classic + BLE).
  • Ultra-Low Power Management: Advanced power-saving modes (Deep Sleep as low as 10µA) for battery-operated remote sensors.
  • Full ESP-32S Compatibility: Direct drop-in replacement for the ESP-32S module footprint, utilizing the same SMD-38 package.
  • Massive I/O Integration: Features 38 pins supporting capacitive touch, Hall sensors, SD card interfaces, Ethernet, high-speed SPI, UART, I2S, and I2C.
  • Hardware Security: Built-in cryptographic hardware accelerators for AES, SHA-2, RSA, and ECC to protect data transmission.
Usage Scenarios
  • Business & B2B: Perfect for mass-producing industrial gateways, smart meters, and wireless sensor networks where reliability and dual-core performance are mandatory.
  • Smart Home & Building: Used in Wi-Fi-enabled lighting systems, HVAC controllers, and security cameras requiring Bluetooth provisioning.
  • Single User / Maker: The go-to module for DIY Home Assistant nodes, retro gaming emulators, and custom wireless audio streamers.
Q: Is this module 100% compatible with the ESP-32S?
Yes. It uses the same physical dimensions and pinout mapping as the ESP-32S. If your PCB was designed for an ESP-32S, this module will fit and function perfectly.
Q: Why should I choose the Dual-CPU (Dual-Core) version?

Single-core chips can sometimes experience “stuttering” or disconnects if the application code blocks the processor while the Wi-Fi stack is trying to run. The Dual-CPU version prevents this by splitting tasks across two cores

Q: Does it come with an antenna?

This module features a high-gain onboard PCB antenna. Some variants also include an IPEX (U.FL) connector for external antenna attachment; please verify your specific model variant if an external antenna is required

Q: Can I program this with the Arduino IDE?

Absolutely. It is fully supported by the Arduino IDE, MicroPython, and the professional Espressif ESP-IDF framework.

Q: Is it suitable for battery-powered projects?

Yes. When configured in “Deep Sleep” mode, the module consumes very little power while retaining its RTC (Real-Time Clock) memory, allowing it to wake up on a timer or external trigger

Q: What is the maximum Wi-Fi range?

With the onboard PCB antenna, the range is typically up to 100 meters in an open-field environment. For longer distances or metal enclosures, we recommend using a version with an external antenna connector
