Default Arduino Pin Mappings

The following table shows how the shield connects your Arduino’s pins to the motor drivers’ pins:

Arduino Pin VNH5019 Driver Pin Basic Function

Digital 2 M1INA Motor 1 direction input A

Digital 4 M1INB Motor 1 direction input B

Digital 6 M1EN/DIAG Motor 1 enable input/fault output

Digital 7 M2INA Motor 2 direction input A

Digital 8 M2INB Motor 2 direction input B

Digital 9 M1PWM Motor 1 speed input

Digital 10 M2PWM Motor 2 speed input

Digital 12 M2EN/DIAG Motor 2 enable input/fault output

Analog 0 M1CS Motor 1 current sense output

Analog 1 M2CS Motor 2 current sense output

See the Pinout portion of Section 4.b for detailed descriptions of the VNH5019 driver pins and Section

5 for a schematic diagram of the shield. See Section 6.a for instructions on how to customize your

board’s Arduino pin mappings if the above defaults are not convenient.
