Power Supply - 5V, 4A

This is a high quality power supply manufactured specifically for SparkFun Electronics that packs a lot of power; 20W at 5V and 4000mA! This power supply helps to squeeze every drop of performance out of a board like the Jetson Nano, but can also work to power addressable LED strips and projects that require higher power requirements.

Note: While Tech Support was verifying this product datasheet from the supplier, they found that this supply will begin to drop voltage when drawing more than 2 amps up to a maximum of a .25v drop at 4 amps. They have notified the supplier & have identified the root cause as the length & gauged of the cable used from the power supply to the barrel jack. While this has not caused any in house issues powering boards like the Jetson Nano, if you application demands it, they recommend shortening your cable to 50cm
