Hello everybody,
I am trying to connect Pixhawk Cube to the motors, and I am using Pololu G2 (Pololu G2 High-Power Motor Driver 18v17 ), which is recommended in Ardupilot’s website ( Brushed Motors — Rover documentation ) - well, at least verified! - . The problem is I couldn’t figure out connections between the Pixhawk & the driver.
Looking at the connections:
Right Side (4 pins):
GND , VIN → I connect them to my power supply’s ground and + voltage (around 20V).
OUTB, OUTA → I connect them to the motor.
Left Side (8 pins - but 4 of them enough for using the motor as I tried with power supply):
GND → ?
DIR → ?
PWM → ?
PLT → ?
There are 3 outputs (-, +, S) going from the Pixhawk. I tried a power supply first, and by using these 4 pins I was able to make the motor work ( I guess I connected GND to ground, PWM and PLT to 5V output, DIR to either ground or 5V - all from the power supply, second channel). Note that, I was controlling the motor’s speed by changing the battery power (VIN of the left side), there was no PWM control. Now I want to connect Pixhawk to it, but don’t know what connections should be made.
Thanks in advance!
