Description
Feature:
5V 4-Channel relay module expansion board, is convenient to control all kinds of electrical appliances and large current devices. It can also be directly controlled standard interface by microcontroller to implement various of function experiments together with breadboard and Dupont thread. The relays on the modules are independent of each other, the output is normally open or closed. The LED will light up when the relay triggers in low level, to indicate the current relay working condition.
Package Include:
2pcs 5V 4-Channel Relay Module
