  • I hope you’ve found your answers before this, but if not: The servo PWM pulse is expected to be between 1000 and 2000 microseconds (average). Some servos will try to achieve positions between 500 and 2500 microseconds (positional servos may try even if they are physically incapable, so be careful!). Sending a pulse of 4500 or 7000 will just get ignored, as they are out of range. So basically you told the servo to stop (1500 = “center” for positional servos or “stop” for continuous rotation), then you sent pulses out of range that got ignored. One final note is that most hobby servos expect a 6000 to 9000 microsecond space between command pulses, and may not respond to changes from pulses sent before 6000 microseconds have passed.

    Hope this helps!

  • Some of the documentation images seem to show the microSD card slot behind the ‘top’ of the screen, others seem to indicate the card slot is behind the ‘bottom’. Can I get some clarification on this from someone who has played with one? Thanks!
