HHKB Bluetooth mod
==================
See this article:
http://geekhack.org/showwiki.php?title=Island:20851
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)
