2.1 EVM Setup and Mode Select

The following sections provide an overview of the hardware connections necessary to evaluate the both the DRV8421A and DRV8421B variants as well as both supported load configurations.

The Mode Select jumper (J2) must always be populated in one of the two configurations. This jumper allows the user to select from a brushed-DC or stepper motor mode.

The Step Select jumper (J10) and Sleep Enable jumper (J1) depends on which variant is populated on the EVM.

All shunts on jumper (J7) must always be populated to allow MCU signals to control the DRV8421.

Note: All setups and mode selections remain the same for both the DGQ and DFU packages.
