Raptor GCM44 by John Deere®

The GCM44 is a general-purpose control module with two CAN buses, and configurable discrete inputs and outputs including analog inputs, digital inputs, high-side driver outputs, and two low-side driver outputs that support precision current control. The GCM44-2409 also contains an internal accelerometer and PCB temperature sensor and will wake on application of battery power or via CAN2.

The GCM44 is one of the John Deere M Series Raptor™ Rugged Production Controllers that use a software development process based upon MATLAB/Simulink and Raptor-Dev which significantly speeds up algorithm development by using automatic integration and code generation. In addition, developers can quickly evaluate application software using simulation and automated testing.
