With infrared function to test remote controls for air conditioners, amplifiers, etc., checking if they are functional or lack power. Module board is compatible with all 20-pin and 24-pin ATX computer power supplies. Features a light-touch switch rated for 550,000 cycles for reliable operation. Includes a reserved XH2.54-2P terminal (overhanging), allowing two external wires to control the ATX power supply on/off via a microcontroller I/O port (5V) or an external switch (easy to enclose or modify). The board provides 6 USB ports, each delivering 5V with a maximum current of 2.1A, suitable for charging mobile phones, tablets, power banks, flashlights, and electronic device aging tests. High-current terminals (rated for 300V withstand voltage and 20A current) eliminate poor connections commonly associated with standard terminal blocks or screw-type terminals. After power-on, the module outputs +12V, -12V, +5V, 5VSB, and +3.3V, maximizing ATX power supply utility. Output: 5V/2A Wiring terminals: up to 20A USB ports: 6 Power outputs: +12V, -12V, +5V, 5VSB, +3.3V Power output indicators: +12V normal = blue LED -12V normal = blue LED +5V normal = red LED 5VSB normal = red LED +3.3V normal = red LED Compatible with all 20-pin and 24-pin ATX power supplies Type: B (without case) Color: Black Material: PCB and components Package includes: 1 x Adapter board Note: Color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
