Page 14: Hardware Design
5 Hardware Design 5.1 Design in Considerations It’s required to connect the following signals correctly to make UM220-INS series modules work properly. The VCC module is of good monotonicity, and undershoot and ringing are required to be guaranteed within 5% VCC. If VCC is powered off and then rebooted, the power off time must be greater than 10ms. -

VCC_RF Figure 5-1 UM220-INS Active Antenna (+3V) Solution If the UM220-INS series modules use an active antenna other than +3V, the bias voltage V_BIAS required by the antenna is used to power the antenna through the feeding inductor. Figure 5-2 UM220-INS NF Active Antenna (Other than +3V) Solution If the UM220-INS series modules use a passive antenna, connect the antenna to the RF_IN directly, and VCC_RF can be left floating. -
Page 16: Serial Port
5.3 Serial Port The serial ports of UM220-INS series modules are of LVTTL level, use a RS232 converter for the PC connection.

The normal direction of the shield is Z axis, the long axis is Y and the short axis is X. 2. The coordinate of the module must be consistent with the vehicle’s, which means: X-axis and R-axis are parallel in the same direction, Y-axis and F-axis are parallel in the same direction, and Z-axis and U-axis are parallel in the same direction.

Page 18: Installation Of The Module
5.6 Installation of the Module UM220-INS series modules must be rigidly connected to the vehicle body and firmly fixed. 1. The antenna should be installed with the front facing up as much as possible and firmly fixed; ensure that the elevation angle of the environment where the antenna is located is greater than 15 ° and the space is unobstructed. -
Page 19: Installation Options Of The Module
Free Installation (Default Mode) UM220-INS series modules integrate a three-axis gyroscope and a three-axis accelerometer, with a built-in self-calibration algorithm, which supports the free installation of the module with respect to any installation angle of the vehicle coordinate system, such as, the completely horizontal installation, inclined installation at a certain angle, and flip installation. -
