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/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/can pass 20A current), solving the problem of poor wiring and bad wiring caused by terminal blocks and screw type terminals. The module outputs +12V, -12v, +5V, 5VSB, +3.3V after power on, which enables you to make better use of the ATX power supply and facilitates your use. Output: 5V/2A Wiring terminals:Max 20A output USB port: 6 groups 5 power outputs: +12V, -12v, +5V, 5VSB, +3.3V 5 types of power output indicators: +12v normal output = blue displayed -12V normal output = shows blue +5V normal output = shows red 5VSB normal output = red display 3.3V normal output = red display Compatible: with all 20-pin and 24-pin computer power supplies type: B: without case Colour:Black Material:PCB+components Package Contents: 1 x Adaptor board Only the above package content, other products are not included.
