Frequently asked questions

  1. Does the module require another motor controller or ESC?
    No! The motor controller (ESC) is integrated in the motor.
  2. How can I change the settings on my motor module?
    The easiest way to change motor settings is through our GUI, which will be available soon. You'll need to plug the module's communication wires into a USB to UART chip (FTDI or CP2102) and connect that to your computer. You can also use a select few flight controllers as a passthrough to our GUI.
  3. What communication protocol do you recommend?
    The speed firmware communicates via DShot, MultiShot, Oneshot, PWM, and UART, and the position firmware communicates via step/direction, UART, and PWM. For the speed module and a standard FC, we recommend DShot. For the position module, we recommend UAR because it is fully featured.
  4. What's the difference between the two firmware choices?
    The two primary differences are the communication protocols and the style of controller. The speed module has a velocity controller, while the position module has a position controller.
  5. Will I be able to change the firmware on my module?
    Yes, you will be able to update your current firmware or flash different firmware through our GUI.
  6. How do I connect my module to a flight controller, arduino, etc.?
    You can directly connect the modules to any FC, arduino, etc. Use the datasheet to figure out which communication connections are associated with each pin. You’ll also have to connect to power and ground. Datasheets are available on the product pages.
  7. Don’t RC cars already have sensored motors?
    Yes, but RC car motors have 3 discrete hall sensors, while IQ modules use a magnetic rotary encoder. This new technology gives us extremely precise motor position information, which allows us to drive the motor more efficiently, smoothly and accurately.
  8. Do IQ motors use field oriented control (FOC)?
    Sort of. FOC belongs to a family of control called vector control. IQ motors do vector control, but not FOC. You should expect the same efficiency benefits of an FOC motor plus other advantages like seamless reversibility, faster reaction time, and position control.
  9. For quads, what flight controller do you recommend?
    IQ modules work with any standard flight controller.
  10. What voltages can I use with the Speed and Position Modules?
    Use any voltage between 5V and 25.2V (Lipo 2S to 6S). We recommend using the external capacitor for anything above 3S.
