1 Channel Relay Module 5V low level trigger interface Board Shield For PIC AVR DSP ARM MCU Arduino

The module uses genuine quality relay, normally open interfaces   Using SMD optocoupler isolation, driving ability, stable performance   The module can be high or low by a jumper setting trigger   Fault-tolerant design, even if the control line is broken, the relay will not operate   The power indicator (green), the relay status indicator (red)   The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.
