1.1 Power Connectors

The CPG005_DRV88xx Customer EVM offers access to VM (Motor Voltage) power rail via a terminal

block (J1). A set of test clips in parallel with the terminal block allows for the monitoring of the input power

rail.

User must apply VM according to datasheet recommended parameters.

NOTE: VDD for logic and microcontroller is derived from USB interface.

1.2 Test Stakes

Every pin on the DRV88xx device has been brought out to a test stake. A label on the silkscreen identifies

each signal.

For those pins that change functionality depending on device flavor, a table is provided with corresponding

function name on its particular column.

1.3 Jumpers

There are only three jumpers the user must configure as detailed below. Default configuration assumes

microcontroller resources are being utilized. As an alternative, a variable resistance is provided on the

opposing jumper configuration.
