General Hardware Architecture


*Not all shown features available on every model.
Please see the hardware comparison guide or specific product pinouts for exact model information.*

Field Readiness

Deployable with production grade code using supported development environments.

Electromagnetic Compatibility

EMC has been completed for certain automotive applications, but is specific to each use case. Reach out for more details if EMC is required for your application.

  • Radiated and conducted emissions
  • Immunity to conducted transients on power leads
  • Immunity to electrostatic discharge
  • Immunity to electromagnetic fields
  • Immunity to radiated electromagnetic fields

MATLAB Add-on Requirements

To program in MATLAB using the complimentary toolbox you will require the following add-ons from MATLAB:

  • MATLAB
  • Simulink
  • MATLAB Coder
  • Simulink Coder
  • Embedded Coder
  • (Optional) Stateflow
  • (Optional) IEC Certification Kit for ISO 26262

Need more than what is on board? Our products are easily expandable with our CANbus and Ethernet modules. There is a wide range of available add-ons. Contact us to add any of the following:

Specialty
  • Magnetic Pick-Up (0.5 Hz to 20 kHz ; 100 mVAC to 100VAC (RMS))
  • Strain gauge (+/- 19.5 mV to +/- 2.5 Vdc)
  • Thermocouples (Type J, K, T)
  • Battery Cell Voltage Monitor
  • Form C Relay Outputs
  • 30A H-Bridge for DC loads (Solunoids, motors, etc.)

How Does It Work?

The FlexCase is easily expanded by attaching almost any device to the CAN bus or Ethernet network present. We have a number of pre-approved add-ons listed above which make the task even easier and are automatically setup.

FlexBench


Breakout Board (C3),
I/O Connector 1 (C1), I/O Connector 2 (C2), Internal pin.

Current Version: 1.2 – Previous Versions

2D Drawing – PDF

3D Model – CAD

Breakout Board – Altium

Header I/O pins on the back of the FlexBench are Samtec TFM-120-02-L-DH. If a custom board is desired we recommend:

  1. Download the design files for the breakout board.
  2. You can swap the Samtec SFM counterpart if desired. An example part number would be SFM-120-xx-x-x-D(H) where x is selectable based on your application. You can design horizontal or vertical boards.
  3. You may want to add bulk capacitors and overvoltage protection to your custom circuit if desired.
  4. Use the provided mount holes to secure your PCB.
  5. Check the positioning of your design using the provided CAD model.
  6. You can get the board manufactured and assembled at your favourite PCBA supplier.
