Description:
4 Channel 5V Relay Module for Arduino R3, MEGA 2560,  ARM, PIC, AVR, STM32, and Raspberry Pi
5V 4-Channel Relay interface board, each one needs 15-20mA driver current.
Standard interface that can be controlled directly by microcontroller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430) TTL logic.
Equipped with high-current relay: AC240V 10A / DC28V 10A.
Indication LEDs for relay output status.
