The benchtop power board kit provides quick access to common voltages required for physical computing and embedded system development. Features include a power indicator light and an on/off switch. Delivers standard output voltages: 3.3V, 5V, +12V, and -12V. Each output channel includes a replaceable 5A fuse and a corresponding ground connection via binding posts for easy wiring. Equipped with a standard 24-pin ATX connector, power indicator, and power switch, ideal for DIY low-voltage power supply setups. If using a 20-pin power supply, align the connector with the dot mark on the circuit board when inserting. Compatible with ATX power supplies (also compatible with some BTX types). 24-pin connector with four distinct voltage output groups. +12V to GND: +12V (positive), GND (negative), 12V DC GND to -12V: GND (positive), -12V (negative), 12V DC +12V to -12V: +12V (positive), -12V (negative), 24V DC Note: The -12V output is limited in current capacity (approximately 300mA) and is intended for logic reference, not for powering high-load devices. Label printing may vary slightly between batches, but this does not affect functionality.
