Reset IMU

RST must be high for the IMU to be active.

To enable the IMU when the receiver is powered on, connect this pin to Pin 1 or Pin 2 of the receiver interface connector through a 10 kΩ resistor (recommended).

Can also connect this pin to any stable 3.3 VDC power supply or output configuration to have more control over when IMU is enabled. When using this configuration note that:

  • pin 8 must be pulled low for greater than 100 ms to properly soft-reset the IMU

  • pin has an internal pull-up resistor
