ildo.

2 layer board of 4.81x2.17 inches (122.12x55.12 mm).
Shared on March 30th, 2015 00:31.

ATX Breakout Board with dual USB charging capability. ATX 24pin, EPS12V (also known as ATX12V 4+4 for connecting 4 or 8 pin CPU connector), and PCI-E connector can be connected to provide 3 12V “rails” along with 5V and 3.3V outputs.

Revision: A

Top and bottom ground layers are stitched together to allow better heat transfer and reduce noise.

USB bottom port is powered by 5VSB, top port powered by regular 5V rail fused to 3A.

This board is based on ATX PSU Distributor from eMAKERshop, and ATX Breakout Board designed by Francesco Truzzi.
