2TiWi-uB1 EM Board Description
The TiWi-uB1 EM “Evaluation Module” Board is an evaluation platform for the LS Research TiWi-
uB1 Bluetooth Smart module. The TiWi-uB1 EM Board provides all of the necessary connectors,
jumpers, indicators and switches to test and debug all aspects of the TiWi-uB1 module. The EM
board is intended for evaluation purposes when used by itself or in conjunction with various Texas
Instruments development boards. When used by itself, an on board coin cell battery or external
power supply is used to power the TiWi-uB1 and its various peripherals.
The TiWi-uB1 EM board can be used to evaluate basic BLE connectivity. Additionally it is possible
to put the TiWi-uB1 module into static RF test modes so that RF performance can be evaluated.
Either a Texas Instruments CC Debugger or SmartRF05EB is required to be used in conjunction
with the EM board for programming and debugging. The CC Debugger and SmartRF05EB are not
provided by LSR and need to be purchased separately from Texas Instruments.

3.1 RF Connector
There are two TiWi-uB1 Module versions:
LSR Part Number
Description
450-0103
TiWi-uB1 Module, PCB Trace Antenna
450-0106
TiWi-uB1 Module, RF Castellation (Onboard Antenna Disabled)
Table 2 Module Part Numbers
The TiWi-uB1 EM board includes an on board U.FL RF connector J3 (Figure 1). When used in
conjunction with TiWi-uB1 450-0106, J3 provides an RF connection point to external antennas
or test equipment. When the TiWi-uB1 EM board is used with used with TiWi-uB1 450-0103,
the U.FL connector has no electrical connection to the TiWi-uB1 450-0103.
The TiWi-uB1 is modular certified for FCC 15.247 and IC RSS-210, as well as compliant to the
RF requirements for ETSI EN 300 328 and ETSI EN 301 489. The TiWi-uB1 450-0106 has
modular certification when used with LSRs 001-0001 2.4 GHz Dipole Antenna with Reverse
Polarity SMA Connector.
See the TiWi-uB1 datasheet and antenna user’s guide for further information regarding FCC/IC
modular certification.
3.2 EM Interface Connectors
There are two primary connectors on the TiWi-uB1 EM Board, J1 & J2. These provide a
standard interface to Texas Instruments development platforms. Refer to Table 3 and Table 4
below for details on the signals brought out to the EM connectors J1 and J2.
