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:

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.
 
Color legend: C1 – 8 Pin header, C2 – 30 Pin header, C3 – 4 Pin header, C4 – 30 Pin header, Internal pin. Current Version: 1.0
*All Dimensions in millimeters |
The FlexCase E 1.0 (see previous versions) and R (OEM SBC) are almost identical except for a change of connectors. The FlexCase E is intented for IP rated applications whereas the OEM version is more suited for custom integrations.
