Product Overview

Automotive OEMs and Tiers 1s are working to improve efficiency in all major systems to meet the ever increasing fuel economy standards. This drive for efficiency improvement leads to ongoing development efforts in the electrification of powertrain and chassis systems. As is the case in many new development programs, there is a gap between the initial “one-off” proof of concepts developed in a laboratory and the product needed for high volume production. The S090 Solenoid and Motor Driver engineering development module helps fill this gap.

As engineering teams develop new systems, the needs for electrification can exceed the capabilities of existing ECUs. Rapid controls prototyping ECUs such as Pi Innovo’s OpenECU can be used to develop the controls, but the power requirements for the system will usually exceed the capabilities of an RCP ECU. When you need to bring muscle to your rapid prototype development in a cost effective manner, the S090 Solenoid and Motor Driver engineering development module is designed to be a versatile development tool.
