0V: This is the main logic ground of the Sabertooth 2x32. It is internally connected to B-.
5V: This is a 5V output, and can supply up to 1A of current to devices such as receivers, potentiometers,
microcontrollers or servos.
S1: This is a main signal input. Its functionality depends on the operating mode. Input voltages into S1
should be between 0V and 5V.
S2: This is a main signal input. Its functionality depends on the operating mode. Input voltages into S2
should be between 0V and 5V. S2 can also be set up as an Indicator type output.
A1: This is an auxiliary signal input. Its functionality depends on the operating mode. . Input voltages into
A1 should be between 0V and 5V.
A2: This is an auxiliary signal input. Input voltages into A2 should be between 0V and 5V. A2 can also be
set up as an Indicator type output.
