J2 DC power jack
This is a generic DC jack connector with a 2.1mm center pin (will be 2.5 mm on ALIX.1B).
Recommended input voltage is +12V. Supply current is about 0.4A at 12V, without any miniPCI
adapters or USB devices installed. Absolute maximum rating for the FAN5026 switching regulator is
16V, be careful when connecting to unregulated sources such as solar batteries etc.

J5 PS/2 keyboard / mouse
Keyboard and mouse are combined on one connector to save space and avoid a tall stacked
connector. Use an off-the-shelf splitter if both keyboard and mouse are needed. Please note that not
all splitters use the same pinout... If the BIOS hangs, swap keyboard and mouse.
