‘FlexControl 14’ page 4/11 Firmware version 1.x
Each analog input has an ‘auto-calibration’ feature, allowing the attached potentiometer to operate
in limited range and yet to give full-range 7-bit values. The extreme points can be reset anytime with the
help of
‘FlexControl Configurator’
tool.
Most suitable sources of stabilized 5V supply for
potentiometers are shown on the pictures on the left and
right.

Digital / PWM outputs
All of the 14 output pins can be configured as
digital
and are suitable for active or inductive loads –
relays, fans, LEDs, etc.
Also, all of the 14 output pins can be configured as
PWM
and are suitable for servo motors. The PWM
resolution is 100 us with maximal period of 25.5 ms.
