1 nos 5V 8 Channel Relay Module Board For Arduino Raspberry Pi

The DC 12V 4-Channel Relay Module is a compact relay interface board designed to control multiple AC or DC loads using Arduino, PIC, AVR, ARM, DSP, PLC, and other microcontrollers. It features 4 optocoupler-isolated channels, low-level trigger inputs, and individual relay status LEDs for easy monitoring. Each relay supports up to 250V AC/10A or 30V DC/10A, making it suitable for home automation, industrial control, lighting, motors, pumps, and DIY electronics projects.

The DS1307 RTC Module is a reliable real-time clock module for accurate time and date tracking in Arduino, ESP32, Raspberry Pi, STM32, and other embedded projects. It uses the I²C interface, includes an AT24C32 4KB EEPROM for data storage, and provides a 1Hz output signal for timing applications. A CR2032 backup battery holder maintains time during power loss; the battery is not included.
