Product Overview

The M250 module is a compact electronics module that is suited to computationally intensive applications requiring a chassis mounted, sealed metal housing with IP67 environmental protection. Based on the same Freescale MPC5534 32-bit microcontroller as the M460, the M250 features 2 CAN interfaces, precision analogue 12-bit inputs and configurable high current switching outputs. A group of inputs and outputs are particularly suited emissions control applications with appropriate sensor signal conditioning and drive characteristics.

At additional cost it is possible to build options that will modify the hardware specification within certain limits.

Custom Variations

Pi Innovo engineering services can rapidly develop custom ECUs based on the resusable block designs within OpenECU.
