With infrared function to test things like TVs, air conditioners, water heaters, 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.
