Evaluation Board Overview
There are 2 banana jacks, 4 LEDs, one wake up button, one connector for the uIO and a set of headers for
jumper configurations on the evaluation board. The functionality behind these components is explained in the
following chapters. The distribution of these elements on the board can be observed in the figure below:

Banana Jacks
The SBC is usually supplied through the
VBAT
(X6, typ 13.5 V) and
GND
(X9) banana jacks (alternatively see
Chapter 6.1 to supply it with the uIO stick).
The
VCC1
(X11
, 5 V or 3.3 V, depending on the SBC’s version) and
VCC2
(X11, 5 V) screw terminals provide
the regulated output voltages of the SBC. The voltages
VCC1
and
VCC2
are simultaneously used to support
signal LEDs at the output clamps.
The charge pump stage of the SBC drives two MOSFETS at the evalboard. One to protect SW against reverse
polarity, the other is used as a VBAT power switch, supporting the SW (X7) terminal.
3.
Buttons
The wake up button (WK) wakes up the SBC (from Sleep and/or Fail Safe Mode), if the corresponding jumpers
are properly configured (see Chapter 6.4 for more information).
4.
LED’s
The
LED FO
(D8) and
LED GPIO
(D7) indicate the voltage level of the FO/GPIO pins, if the corresponding jumpers
are properly configured (see Chapter 6.4 for more information).
The
VCC1 LED
(D1) lights, if VCC1 is enabled and the
VCC2 LED
(D5), if VCC2 is enabled, if the corresponding
jumpers are connected (see Chapter 6.3 for more information). Only one LED (
LED FO
or
LED GPIO
) can be
used at a time.
