Power and Communication Connectors
The EVM offers terminal blocks for the application of power and motor outputs, as well as digital
input/output (I/O) and communication. This section briefly describes the functions. The pin assignments
are described in

1.2.1.1
Power Connector
The VB power rail (typically 12 V) must be externally supplied. The power for the external MCU and other
analog and digital functions are supplied by the regulator implemented in the DRV3204-Q1 device.

1.2.1.2
Motor Outputs
A brushless DC Motor is connected to the EVM through the motor outputs.
1.2.1.3
Analog and Digital I/O
The analog and digital I/O and SPI communication of the DRV3204-Q1 can be used through the
connector.
connector.
1.2.2
LED
The LED turns on when the DRV3204EVM power is supplied.
1.2.3
Switch
Switch1 is connected to the enable input (ENABLE) pin of the DRV3204-Q1. DRV3204-Q1 is enabled by
turning this switch ON. Switch3 is for disabling the watchdog function. When you want to disable the
watchdog function, this switch must be set to the RES position.
