+RN-42
+=====
+
+HHKB key switch power control
+-----------------------------
+MOS FET Nch: BSS138 or IRLML6344T, either works and no apparent difference.
+Normally on(pull-up) or off(pull-down)? interms of power saving it prefers pull-down?
+
+Pull-down will be better for power saving, normally off.

+Used Timer
+----------
+
+8MHz clock
+----------
+1) 16MHz xtal with system prescaler div2: F_CPU=8MHz, F_USB=16MHz
+2) 8MHz xtal with div1: F_CPU=8MHz, F_USB=8MHz
+Hardware USART doesn't work at 115200bps with 8MHz(F_CPU).
+
+workaround:
+a) use Sotwre serial for communcation with RN-42
+b) reduce baud of RN-42 to lower rate;(factory default is 115200bps)
