1CH 5v Relay Board High/Low Level Trigger with Optocoupler music player remote The low-level peripherals on the1CH 5v Relay Board High Low Level Trigger with Optocoupler The 5V Single Channel Relay Module high level or low level trigger relay is a great little tool for anyone working with Arduino, 8051, AVR, PIC, DSP, or ARM microcontrollers. This module lets you control high power devices with either a high or low level signal. It can handle up to 15A at 125V AC or 10A at 250V AC. Plus, this microcontroller relay module is small (50 x 25 x 20 mm) and
