 Power consume
 =============
 Switch board
 ------------
 5V
 18mA full scan/no power control
 16.5mA full scan with power control of POWER_ON/POWER_OFF in matrix.c
 3.5-6mA 60ms watchdog timer sleep iwrap/main.c

 - the longer sleep time the less power is consumed.
 - power control of swtich board must be needed.
 FET switch may be better, though 18mA is with in port sink current limit. In current design switch board ground is connected to PB5 pin and power it on by making the pin low.

 Blueguiga WT12
 --------------
 3.3V
 -42mA startup/searching/connecting
 19-23mA connected
 4mA -8mA not connected

 iWRAP sleep command may not work. to be looked into.

 Power Over all
 --------------
 5V
 -65mA startup
 17-24mA idle/not connected
 -42mA connecting
 32-37mA idle/connecting(with sleep)
 50-53mA typing/connecting(no sleep)
