1 Overview
Thank you for purchasing and using UB4B0 GPS/BDS/GLONASS/Galileo
ALL-Constellation Multi-Frequency High Precision OEM Board. The UB4B0 can provide
reliable centimeter-level accuracy and high accuracy heading output at high update
rate .UB4B0 employ the new generation all-constellation multi-core high precision SoC
chip, NebulasII (432 channel tracking), based on mature base line chip (XINGYUN), 55nm
low power consumption，built in broadbandADC and anti-interference unit，integrated two
600MHzARM processor and special High speed floating point processor，provides more
powerful satellite navigation signal process ability. UB4B0 provide millimeter-lever
carrier-phase observation data and centimeter-lever RTK position Output, supports
advanced multi-path mitigation and low angle tracking；UB4B0 is suitable for high
precision surveying and mapping application, especially for geodetic surveying
engineering survey, deformation monitoring, mechanical control, meteorological
monitoring, Precision agriculture, Continuous operation reference station（CORS）etc.
advanced instantaneous RTK and long-distance RTK.

2 Hardware Design in Considerations
To keep UB4B0 functioning normally, the following signals need to be connected correctly：
The module VCC power-on has good monotone, the initial level is lower than 0.4V,
and the undershoot and ringing should be guaranteed within 5% VCC
It is recommended to use a power chip with current output capacity greater than
2A to power the board
3 Installation
This section contains the list of the product package and the details of product
installation.
3.1 Package Inspection
Please check the contents of the package carefully after receiving the package of UB4B0：
UB4B0 board and EVK suite (or evaluation board) (or enclosure)
User manual (CD attached)
Command manual (CD attached)
UPrecise software (CD attached)
3
MMCX antenna cable
Cross serial Port cable
3.2 ESD Protection
A lot of components onUB4B0 susceptible to electrostatic damage, which affects IC
circuits and other components. Please follow the instructions below for ESD protection
before open the plastic package:
Electrostatic discharge (ESD) can damage components. Please use under anti-static
work bench, a conductive foam pad, and at the same time, wearing an anti-staticwrist
strap. If ESD workstation is not available, wear an anti-static wrist strap and attaching
it to metal parts of your industrial PC in order to obtain protection against static
electricity.
Please use the edge of the board, avoiding to touch the components on the board
while fetching or put the boards
Please carefully check for obviously loose or damaged components after removing
the package from the boards. Any questions, please contact your local dealer.
Please save package boxes and plastic containers，for storage and transport.

1. RF Part
The receiver gets filtered and enhanced GNSS signal from the antenna via a coaxial cable.
The RF part convert the RF input signals into the IF signal, and convert IF analog signal
into digital signals required for NebulasII die (UC4C0).
2. NebulasII SoC（UC4C0）
NebulasII (UC4C0) is Unicode’s new generation high precision GNSS SoC with 55nm
low power design, supports up to 12 digital intermediate frequency or 8 analog
intermediate frequency signals, which can track 12 navigation signals with 432 channels.
3. 1PPS
UB4B0 provides1 PPS with adjustable pulse width and polarity and 1 output pulse width.
4. Event
1
UB4B0 provides 1 Event Mark Input.
5. I/O
Power input, data communication port, pulse trigger, LED etc.
3.4 Installation Guide
UB4B0 is delivered as a board, users can flexibly assemble according to the scenario and
the market need. Figure below shows the typical installation of UB4B0 with evaluation kit
(EVK), users can also use other enclosures to install receiver, using the same method.

For efficient installation, please get prepared for the following items before installation:
UB4B0 EVK suite (or evaluation board) (or enclosure)
User manual
Command manual
UPrecise software (CD attached)
Qualified antenna
MMCX antenna cable
PC or Laptop with serial ports (Win7 and above), with UPrecise installed
After the above preparation is made, please follow the steps below to install: ：
Following the steps below to install the device:
1. Align UB4B0 positioning holes and pins with EVK, and fix UB4B0 in the EVK. EVK
provides power supply and standard communication interface for the board, to

, and so on)..
Figure 3-3 Installation Step 1
2. Select a GNSS antenna with appropriate gain, and mount it in an open sky area.
Connect the antenna to J1 MMCX port of UB4B0 via coaxial RF cable.
Figure 3-4 Installation Step 2
NOTE: The RF connector of the board is MMCX, please select the appropriate cable.
The signal gain to board RF connector should be within 25 to 35dB. The Antenna
connector provides 5VDC antenna feed.
3. Connect the PC with EVK through serial ports, or through Ethernet ports.
