- 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)
