She finally found it at 2:47 AM. A single text file, no formatting. The header read:

While official PDF datasheets for this specific generic board can be difficult to source compared to standardized ICs like the MPU-9250, the following parameters define the :

| Pin | Label | Function | |-----|-------|----------| | 1 | ENA | Enable Motor A (Active HIGH, usually tied to PWM) | | 2 | IN1 | Motor A direction input 1 | | 3 | IN2 | Motor A direction input 2 | | 4 | IN3 | Motor B direction input 1 | | 5 | IN4 | Motor B direction input 2 | | 6 | ENB | Enable Motor B (Active HIGH, usually tied to PWM) |

VMS (12V) ----> [LM7805] ----> +5V Logic (when jumper on) | [L298N IC] <------ Control Pins (ENA, IN1, IN2, etc.) | |---> Motor A (OUT1, OUT2) |---> Motor B (OUT3, OUT4) | GND --------> Common Ground

It is AEC-Q200 Qualified , making it suitable for automotive environments where vibration and temperature fluctuations are extreme.
