Use Case
Easy development at the desk
Operation confirmed with Ubuntu 20.04 LTS.
So you can easily develop and run a variety ofapplications using OSS. The small board allows you towork on your desk, making it a great introduction toMobility application development.

Practical development in vehicles
By connecting to the ECU using the vehicle
interface, users can develop integrated intothe vehicle. Ideal for more practical vehicle
application development using various ECU
data such as IVI/Powertrain /Body.
