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.

--------------
|
|
3.3V
|
|
-42mA startup/searching/connecting
|
|
19-23mA connected
|
|
4mA -8mA not connected
|
|
|
|
iWRAP sleep command may not work. to be looked into.
