Description

This just the PCB for a small USB powered busboard contains a meanwell power brick capable of supplying up to 410 mA on the +/-12V rail. It is powered using a 5V usb charger capable of delivering 2.5A. The 5V is also available on the bus board direct from the usb charger.

Like with any power supply you should not run it near it limit but 80% is enough for a mini case or for benchtop testing.

Dimensions:
20cm X 3cm

The concept was originally conceived by Tom Whitwell!

Includes small USB A to USB B cable.

The concept was originally conceived by Tom Whitwell! Big thanks to MMI for the inspiration who also make a USB power busboard using the same meanwell power brick for generating +/-12V.
