2TiWi-uB1 EM Board Description
The TiWi-uB1 EM “Evaluation Module” Board is an evaluation platform for the LSR 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:

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.Figure 3 shows an example of a Host Board
with the mating connectors that will accept a TiWi-uB1 EM Board.
