Power From The PS/2 Mouse Port
« on: August 09, 2003, 09:05:16 PM »

PS/2 mouse port
PS/S mouse port has +5V power output for powering the mouse connected to it. You can get small amouts of power from this port for your own circuits. The computer can turn the PS/2 mouse power off for some time when it initializes the mouse. The mouse does not take much current, so the power capability of this port might not be much (I guess that you can take around 100 mA safely). The pinout is same as in PS/2 keyboard connector: +5V power is at pin 1 and ground at pin 2. The pin numbering is also the same (looking at the connector on the back of the computer):
