1. Evaluation Board Overview

There are 4 banana sockets, 5 LEDs, three buttons, one connector for the uIO and a set of headers for
jumper configuration in the evaluation board. The functionalites will be explained in the next chapters. The
distribution of these elements in the board can be observed in the following figure:

2. Banana Sockets

The SBC is usually supplied through the VSUP input and GND banana sockets.
The VCC1 output (5 V or 3.3 V, depending on the SBC’s version) and VCC2 (5 V) banana sockets provide
the regulated voltages from the SBC. The voltages VCC1 and VCC2 are used to supply the VCC1 and VCC2
supply indication LEDs which can be disconnected via the jumpers directly next to the banana outputs of
VCC1 and VCC2.

3. Buttons

In the upper right corner there are three buttons.

 Test Button for enabling test mode (press during SBC Init-Mode when sending arbitrary SPI command)
 Reset Force this button is connected in parallel to RO output of SBC and will connect RO line to GND

when pressing to force a low signal on RO

 Wake this buttons will do a voltage transition on the wake input of SBC to trigger an external wake

4. LEDs

In the upper left corner are 3 LEDs to indicate the state of the Fail-Outputs. The LEDs can be disconnected
via the jumper directly under the LEDs. There are also two indication LEDs for the status of VCC1 and VCC2
(see behind the banana sockets for VCC1 and VCC2) which can be also disconnected via the jumpers directly
next to the banana connectors of VCC1 and VCC2

5. Connectors

5.1. uIO Connector

The uIO Connector is used for connecting to the uIO stick, but can be also used to access the uC
interfacing pins. The pin distribution of the connector is shown in the following figure:

5.2. Digital IO Connectors

This connector can be used to access the RXD and TXD pins of the appropriate CAN and LIN transceivers

5.3. Transceiver Connectors

Those connectors can be used to connect to the transceiver outputs LIN1-LIN4 and to CAN.
