Ubisense – Ultra-Wideband Location System – Modular Ubitag V2.0

Integration information

The dimensions of the module PCB are shown below:



When mounting the tag on another device care must be taken to avoid occlusion of the antennas

by tall components, shielding, or mounting screws. There should be an air gap of at least 1mm

left around both of the antennas to avoid detuning.

While the connector provides some mechanical fixing it is not recommended that this is the only

fixing point. A double-sided pad has been supplied that can be fitted to the top of the screening

can to securely fix the module to a PCB.

When designing the PCB it is recommended that there is no ground plane underneath the

module.

Power should be supplied on the following pins of the header:

2.3V-5.25V DC power input: Pin 3

Ground: Pins 5,6,9,10,14,18,19

A number of pins on the module’s header may be used for digital input/output and analogue input.

Note that application-specific use of these pins will require Ubisense to write modified firmware

for the device, and therefore integrators wishing to make use of these features should contact

Ubisense in the first instance.

The header used on the module is a Major League TSHS-5 10-D-04-A-F-LF, a standard 1.27mm

pitch through-hole pin header. The recommended connector to use with the module is:

Connector: Major League LSSHS-5 10-D-06-F-TB-P-LF (SMD)
