SNS08A Board
The SNS08A board provides direct control of a sensor input system, as well as control of
drive I/O. A drive I/O control signal is transferred to the DRV08A board for driving.
Measures to cope with chattering and noise during sensor control are provided by software.
The sensor input system controls the buzzer, touch panel, magnetic card reader, and key-
board, in addition to various sensors.
