Overview
Description
The R-Car M3e can be used in a wide range of automotive applications requiring medium-class computing, including for example In-Vehicle Infotainment, low-end integrated cockpit, connected gateway, central server.
A 2GHz version (M3e-2G) is also available, providing increased CPU power.
The R-Car M3e(-2G) is fully software-compatible with the R-Car H3e(-2G), so existing software resources can be reused effectively.
