1Introduction

The purpose of this document is to give guidelines for use and integration of the TeraRanger

Hub Evo board using a USB or UART communication interface. For streaming distance data

via UART, please see instructions on how to use the UART board in section 2.2. Instructions

on how to use Hub’s onboard Internal Measurement Unit (IMU) are available in section 5.6.

TeraRanger Hub Evo external dimensions are illustrated in Figure 1. The board provides two

mounting holes, both designed for M3 screws. The straight distance between mounting

holes is 45.5mm. Figure 2 illustrates external dimensions of the UART board.

2.1 Compatibility with TeraRanger Evo sensors

TeraRanger Evo is compatible with the following TeraRanger Evo sensors:

● Evo 60m

● Evo 3m

● Evo 600Hz

Up to 8 TeraRanger Evo distance sensors (of one type) can be connected to the Hub Evo

board for multi-axis, multi-sensor ranging operations. TeraRanger Evo sensors use a

two-part construction where the black colored optical sensor module simply clips to the

yellow colored backboard for power management and communication.

2.2 Handling during system assembly

Please follow these simple steps showing how to connect 8 TeraRanger Evo sensors to the

TeraRanger Hub Evo.

Step 1. Connecting the cable to the sensor

Start by plugging the flat flex cables (FFC) to the sensor’s FFC connector.

Figure 5. Open, Insert, Close (sensor)

Note that each of the FFC connectors need to be manually opened and then closed when

connecting the Flex Cables as shown in Figure 5. For easier opening you can gently pull the

small locking ‘tabs’ on the sides of the connector before pulling the locking mechanism

down. You may find this easier with tweezers. The locking mechanism has to be pulled out

only a millimeter or less, not entirely! Note that, too much force can damage the sensors’

connector. Also, double check that the Flex Cable is plugged in straight so as to avoid a

potential short-circuit (Figure 6).

When connecting the Flex Cable, make sure that the side with conductive tracks is facing

the sensor’s backboard (yellow part) as shown in Figure 7. Connecting the wrong side of the

cable can damage electronics on the hub and the sensor. Once the cable is positioned

inside the connector, close the connector by smoothly pushing the locking mechanism in.

Step 2. Connecting the sensor to the Hub Evo

Follow the instructions above to connect the cables’ other end to the FFC connector on

TeraRanger Hub Evo board.

Figure 8. Open, Insert, Close (hub)

Step 3. Connecting all Evo sensors to the Hub Evo

Continue connecting the rest of the Evo sensors to the central Hub board (Figure 9).

Figure 9. TeraRanger Hub Evo with 8 sensors connected

Once fully assembled, the TeraRanger Hub Evo is ready for testing on your computer. Use

the micro USB cable (provided in the package) to connect the TeraRanger Hub Evo with a

host computer. Instructions on how to connect the system to a host computer or use a

Graphical User Interface are available in section 3.1 and 3.2.

Step 4. Connecting UART board to Hub Evo (optional)

To stream distance data from Hub Evo via UART, please follow these instructions.

Connect the UART board to Hub Evo’s FCI Bergstak 30 pin connector. Please make sure

you connect the UART board only after all sensors are connected to Hub Evo, as the UART

board allows very limited access to FFC connectors 1, 4, 5, 8 on Hub Evo (circled in red).

See Figure 10 for visual instructions.

Two spacers are provided in the package to ensure a more robust connection (Figure 11).

Place these between the Hub Evo and UART board covering the mounting holes. Please

note that you will need M3 screws (not provided) to enable mounting.

Figure 11. Mounting Hub Evo

Last but not least, connect the UART to open-ended cable to the DF13 6 pin connector

located on UART board and the other cable end to the host of your choice.

● TeraRanger Evo sensors and the UART boards should not be connected or

disconnected from the TeraRanger Hub Evo while it is powered

● Do not mount the TeraRanger Hub Evo onto hot surfaces or near other sources of heat

● Take all usual precautions for sensitive electronics such as maintaining a suitable

distance from strong electric and magnetic fields, strong radio emitters, etc.

● During assembly and integration, please observe all common ESD precautions

2.4 Additional interface for custom

requirements

An extension connector (FCI Bergstak 30 pin

connector) is available on the TeraRanger Hub Evo,

located in the center of the board. This connector

allows you to increase the number of communication

interfaces, power supplies and GPIOs, and provides the

possibility to modify functionality and performance of

Hub Evo. Please note that this additional interface is

used by the UAR board, hence custom communication

interfaces can be added only when the UART board is

not used.

Please contact Terabee at [email protected] for more information on additional

communication interface development.
