Overview
The GCM70 is a general-purpose control module. The module has two CAN buses and sports a three-phase motor driver. The eclectic inputs and outputs make this module suitable for a wide variety of general-purpose applications.
The GCM70 is part of a family of rugged, automotive-grade production controllers that use a software development process based on MATLAB/Simulink, known as Raptor-Dev. Raptor-Dev significantly speeds up algorithm development by using automatic code generation. In addition, developers can quickly test application software on their PCs with a built-in onscreen PC simulation.

Frequently Asked Questions (FAQ)
Non-Volatile Memory Corruption
Non-Volatile memory can be corrupted during a write if the module is improperly powered off (i.e., removing power from Batt+ (Pin 68)).
Calibrations
In production programs, it is recommended to store all calibrations in Flash memory (available within the "raptor_target_def" block).
Recovery Procedure (Boot Key)
The GCM70 requires a boot key to recover the module. These can be found in our webstore.
To use the boot key to recover the malfunctioned module, please follow the Raptor-Cal MotoHawk Module Recovery steps provided here and below.
Note: The boot key signal (Pin E on the SmartCraft connector) needs to be connected to the SWG4 pin for the GCM70.
Once the boot key is used, the module will default to a CAN baud rate of 250K, so update the Raptor-Cal settings accordingly.
Power Cycle Instructions:
- Remove all power to the module by turning off the key-switch and then the power supply. Connect the boot key to the bus.
- From Raptor-CAL/Service: Select Program -> click the Recover checkbox -> MotoHawk -> select the RPG file.
- Click OK, turn on the power supply, then the key-switch.
For a full list of steps, see the Raptor-CAL FAQ Page.
Bootstrap
The GCM70 can be forced to remain in the firmware bootloader by applying a bootstrap sequence. The bootstrap sequence is:
| Pin | State for Boot |
|---|---|
| AN1 | High |
| AN2 | High |
| AN3 | High |
| AN4 | |
| AN5 | |
| AN6 | |
| AN7 | |
| AN8 | |
| AN9 | Low |
| AN10 | Low |
| AN11 | Low |
