8 Channel ESP32 Relay Module Board – Wi-Fi & Bluetooth Smart Home Controller in Pakistan

Overview 

The 8-Channel ESP32 Relay Development Board is a professional-grade IoT solution that combines the dual-core power of the ESP32-WROOM-32E with eight high-quality relays. This board eliminates the “rat’s nest” of jumper wires usually found in DIY projects by integrating the microcontroller, power regulation, and relay switching onto a single, robust PCB. Whether you’re building a centralized smart-switch board or an industrial automation controller, this module provides the stability and connectivity you need.

Key Features 

• Integrated ESP32-WROOM: Features the powerful 240MHz dual-core processor with 4MB Flash, Wi-Fi, and Bluetooth (BLE).

• High-Load Switching: Each of the 8 channels can handle up to 10A at 250V AC or 10A at 30V DC.

• Firmware Ready: 100% compatible with Tasmota, ESPHome, and WLED, as well as custom Arduino IDE or MicroPython scripts.

• Professional Input Options: Most models support wide-range DC input ($5V \text{ to } 24V$), making it compatible with standard industrial power supplies.

• Onboard Programming Port: Includes a dedicated header for easy flashing without needing to desolder the chip.
