With infrared function to test things like , air conditioners, , amplifiers, etc., good or bad remote controls or lack of power. Module board is compatible with all 20Pin and 24Pin ATx computer power supplies. With a light touch switch with a life of 550,000 cycles for easier operation. Reserved XH2.54-2P terminal (overhang), two external wires can be used to control the ATX power supply on or off using the microcontroller Io port (5V) or the switch (easy to add a shell for modification). The board contains 6 USB ports, each USB port can output 5V, MAX = 2.1A current, can be powered to mobile phones, tablets, mobile power, torches, electronic products aging, etc. The module uses high-current terminals (terminal withstanding voltage 300V or can pass 20A current), solving the problem of poor wiring and bad wiring caused by terminal blocks and screw type terminals. The module outputs and12V, -12v, and5V, 5VSB, and3.3V after power on, which enables you to make better use of the ATX power supply and facilitates your use.
