Required Equipment

Required Equipment using Interface Board

The following equipment from the evaluation kit is required:

  • 1 x Neonode Touch Sensor Module
  • 1 x FPC cable with connector
  • 1 x Interface Board

Additional required equipment:

  • An Arduino-compatible board. The I2C library described here supports most Arduino-compatible boards.

  • An Arduino development environment, for example Arduino IDE.

  • Soldering kit, or other corresponding equipment

Required Equipment using Neonode Prototyping Board

  • 1 x Neonode Touch Sensor Module
  • 1 x Neonode Prototyping Board 
  • An Arduino development environment, for example the Arduino IDE.
  • USB cable with a Micro USB type B connector

    Make sure that the USB cable transmits both power and data and not only power.

Connecting Sensor Module using Interface Board

  1. Connect the FPC cable to the interface board:

    1. Lift the flip lock on the interface board.
    2. Insert the FPC cable into the end of the connector, with the connector pads facing down, towards interface board. The yellow piece of PCB of the connector on the other side of the cable is facing upwards. Make sure the direction is straight into the connector and the pads have reached the end of the connector.

    3. Make sure the connector pads of the FPC cable are facing downwards, towards interface board. The sensor module risks damage if the FPC cable is connected in wrong direction.

    4. Press down the flip lock.

  2. Connect the Interface board to the microcontroller
    1. On the Interface board, wire the needed onboard connector pads ( GND, DR, I2C_DATA, I2C_CLK, VBUS ) to the microcontroller. For further documentation, please refer to I2C connection, under Electrical Integration
  3. Connect the FPC cable to the sensor module:
    1. Place the sensor module so that the module's connector pads are facing downwards (steel surface upwards).
    2. Insert the sensor module into the connector on FPC cable (yellow piece of PCB of the FPC connector still facing upwards).
    3. Make sure the direction of the pads is straight into the connector, and the pads have reached the end of the connector.

  4. Make sure no object is within the touch active area of the sensor module before connecting power through USB. The sensor module calibrates itself when powered on and an object within the touch active area may interfere with the calibration.

    1. If the sensor module is of the 0° type: place the module on a table with the steel surface facing downwards and with the optical surface facing towards you.

    2. If the sensor module is of the 90° type: place the module on a table with the steel surface facing upwards, so the optical surface is facing upwards as well. Make sure no object is within the touch active area above the sensor module. 

  5. Connect the microcontroller to the host system

  6. The green onboard LED of the interface board will turn on to indicate power transfer.
  7. Use our example program in our library to verify that everything is working as expected, Arduino Library.

Connecting Sensor Module using Neonode Prototyping Board

  1. Connect the sensor Module to the Prototyping Board

    1. Place the sensor module so that the module's connector pads are facing upwards (black surface upwards).
    2. Insert the sensor module to the Prototyping Board's sensor port.
  2. The sensor module is now connected to the board, which expose all connections between the sensor module and the board. For details, refer to Electrical Integration. Do not connect power until the following steps have been performed.

  3. Make sure no object is within the touch active area of the sensor module before connecting power through USB. The sensor module calibrates itself when powered on and an object within the touch active area may interfere with the calibration.

    1. If the sensor module is of the 0° type: place the module on a table with the steel surface facing downwards and with the optical surface facing towards you.

    2. If the sensor module is of the 90° type: place the module on a table with the steel surface facing upwards, so the optical surface is facing upwards as well. Make sure no object is within the touch active area above the sensor module. 

  4. Connect power to the sensor module through the USB. 
    1. A red light next to the micro USB port should turn on to indicate power transfer. 


  5. The Prototyping Board is now ready to be flashed. Use our example program in our library to verify that everything is working as expected, Arduino Library.
