Introduction
1.2 Test Points
Test points are provided and labeled according to the inputs/outputs of the DRV8871 motor driver.
Test point “PWM_R” is generated by a TLC555 located on the EVM. If an externally generated PWM
signal is desired, either:
1. Remove the shunt on IN1 or IN2 and connect the external PWM signal to the IN1 or IN2 test point (this
is recommended), or
2. Remove the 0.0- resistor R5 and connect the external PWM signal to the “PWM_R test point. The
“PWM” signal generated by the onboard circuitry EVM is approximately 25 kHz and can be adjusted
from 5% to 95% duty cycle by the potentiometer (R6) located on the EVM.
1.3 Jumpers
The following images illustrate the possible connections to the INx jumpers
