Description
This 50cm power cable is designed to run a LattePanda Sigma single-board computer directly from a standard desktop ATX power supply. It provides a reliable power solution for makers and developers integrating LattePanda boards into PC chassis or custom enclosures.
LattePanda Sigma power integration
This cable bridges a standard 24-pin ATX power supply unit to the LattePanda Sigma motherboard, delivering a stable and dedicated 12V power source for reliable operation.
Dual DC 5.5*2.5mm connectors
The output end is equipped with two DC 5.5*2.5mm male connectors to interface directly with the motherboard power inputs over a flexible 50cm length.
Integrated push button switch
A built-in push button switch controls the power signal directly. This enables convenient on/off switching without repeatedly plugging and unplugging the DC barrel connectors, reducing port wear.
ATX terminal wiring layout
The 24-pin ATX pinout is wired specifically to route power signals cleanly into the dual DC barrel outputs.

Heavy-gauge tinned copper wiring
The harness is constructed using UL1007 16AWG and 18AWG tinned copper wire to maintain efficient power delivery and safe current handling.
