1. The module board is compatible with all 20Pin and 24Pin ATX computer power supplies. 2. Adopting toggle switches makes switch operation more convenient. 3. Reserve XH2.54-2P terminals (suspended), which can be connected to two external wires using the microcontroller IO port (5V) or switch to control the ATX power switch (for easy modification with a casing). 5. The module adopts high current wiring terminals to solve the problem of loose and difficult wiring caused by wiring terminals and screw type wiring terminals. 6. The motherboard comes with a voltage display screen, which displays and monitors the computer power output voltage in real time. 7. The motherboard can output 12V voltage when paired with a DC mother socket, which can also be used as input voltage (DC12V-24V). When using a DC mother socket for input, the motherboard's fast charging interface has voltage output. Parameter: Terminal output voltage:+12V, -12V,+5V, 5VSB, 3.3V 3 USB outputs: Output voltage: DC5V MAX; Output current: 0.1A-2.1A; 1 orange USB port: (Fast charging output interface, supports multiple protocols, requires phone and data cable support for fast charging) Output voltage: 5-12V, automatically adjusted according to protocol; Output current: 2A 1 TYPE-C interface output: Supports PD2.0/PD3.0 protocols; Output voltage: 5V, 9V Output current: 2A DC mother socket interface: can be used as input and output interfaces Compatibility: Compatible with all 20 pin and 24 pin computer power supplies Application: The USB interface can provide power to mobile phones, tablets, mobile power supplies, flashlights, Bluetooth speakers, smart bracelets, small , aging electronic products, and more.
