13 18mA full scan/no power control
14 16.5mA full scan with power control of POWER_ON/POWER_OFF in matrix.c
15 3.5-6mA 60ms watchdog timer sleep iwrap/main.c
17 - the longer sleep time the less power is consumed.
18 - power control of swtich board must be needed.
19 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.
24 -42mA startup/searching/connecting
26 4mA -8mA not connected
28 iWRAP sleep command may not work. to be looked into.
34 17-24mA idle/not connected
36 32-37mA idle/connecting(with sleep)
37 50-53mA typing/connecting(no sleep)
