Page 16: 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. When the module is not powered on, it is necessary to ensure that the power supply and all GPIOs are in a high impedance state or a low level to avoid abnormal operation of the module caused by leakage. -
Page 17: Power Supply Requirements
UM220-INS Series Modules User Manual This module is a temperature sensitive device, rapid temperature changes will result in reduced performance, keep it as far away from any high-power high- temperature air and heating devices as possible. 5.2 Power Supply Requirements 5.2.1 Main Supply (VCC) -
Page 18: Antenna
5.3 Antenna If the UM220-INS series modules use an active antenna, the bias voltage V_BIAS is used to power the antenna through the feeding inductor. It’s recommended to use an independent power as V_BIAS to supply the antenna. If the antenna power supply and the module’s main supply VCC use the same power rail, the ESD, surge and overvoltage from the antenna will have an effect on VCC, which may cause damage to the module. -
Page 19: Reset
UM220-INS Series Modules User Manual 5.4 Reset If the reset pin nRESET of UM220-INS module needs to be used, the following timing requirements must be met between the nRESET and the power supply VCC. During normal operation of the module, pulling down the nRESET pin over 5 ms can also reset the module. -

Page 21: Installation Of The Module
1568± 20MHz. 5.8.1 Installation Instructions The UM220-INS series modules must be firmly connected to the vehicle to prevent any offsets or vibrations between the module and the vehicle. UM220-INS series modules should not be installed in the suspension part of the vehicle (with elastic part). When the vehicle is moving, any change of the vehicle coordinate system will seriously affect the UM220-INS module and prevent it from working normally. -
Page 22: 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. - Page 23 UM220-INS Series Modules User Manual 0 – General installation mode, the input value of the installation angle is relatively coarse (within 10deg) 2 – Automatic installation mode, no installation angle is required. Remark: 1) Choose 2 for free installation mode and 0 for fixed installation;...

Page 24: Module Calibration And Notice
5.8.5 Module Calibration and Notice Self-Calibration After the installation of the UM220-INS series modules, the self-calibration is required to ensure the accuracy of the module output. In the process of the self- calibration, the module estimates installation status parameters and sensor parameters. -
Page 25: Disassembly
UM220-INS Series Modules User Manual Conditions of Completing Self-Calibration The self-calibration is triggered after power on, stop for more than three – minutes; – Good satellite visibility is required during the process of the self-calibration (the number of visible satellites is not less than six, and CN0 is above 30dB), the better the satellite observation quality is, the faster the calibration will be. -
Page 26: Package
Product QR Code (serial number) 7.2 Package Description The UM220-INS series modules use carrier tape and reel (suitable for mainstream surface mount equipment), packaged in vacuum-sealed aluminum foil antistatic bags, with a desiccant inside to prevent moisture. When using reflow welding process to weld modules, please strictly comply with IPC standard to conduct humidity control on modules. - Page 27 Thickness: 2.0mm Carrier Tape Space between: 20mm UM220-INS series modules are rated at MSL level 3, refer to the relevant IPC/JEDEC standards for baking requirements. Please access to the website www.jedec.org to download for details. The shelf life of UM220-INS series modules is one year.
- Page 28 9 Reflow Soldering In order to avoid device falling off, the module should be placed on the top of the main board during welding. Reflow soldering temperature curve is recommended as shown in figure 9-1 below (M705-GRN360 is recommended for solder paste). Note: The module can only be welded once.
