DRV8343S-Q1EVM: DRV8343S-Q1

Prodigy 165 points
Part Number: DRV8343S-Q1EVM

H Team,

my customer would like to control DRV on the EVM with external MCU.

How can the external SPI signal be connected to the EVM without interfering with the MSP430 controlling the DRV normally.

Pls advice.

Thanks, Harry711

    Hi Harry,

    All of the signals running from the MSP430 to the DRV8343 run through a row of zero-ohm resistors (R14 through R36). These resistors can be removed as needed, and the external MCU can be connected to the test points to the right of the resistor pads. These test points are sized/spaced to accept a 100 mil header, which can be soldered to the board for easily connecting external signals.

    Thanks,

    Garrett
