The kit includes the SmartRF Transceiver Evaluation board (TrxEB), which has a number of useful features for development of prototype software, as well as USB connectivity making it possible to connect the board to a PC and control the radio from SmartRF Studio. In short, the TrxEB includes
MSP430F5438 MCU
USB interface
128 x 64 dot matrix LCD
3 axis digital accelerometer
Ambient light sensor
The software examples provided with the kit can be used as a basis for working with the Transceiver Evaluation Board and the connected radio.

SmartRF收發器評估板(TrxEB)
The SmartRF TrxEB is a flexible test and development platform that works together with RF Evaluation Modules from Texas Instruments.
An Evaluation Module is a small RF module with RF chip, balun, matching filter, SMA antenna connector and I/O connectors. The modules can be plugged into the SmartRF TrxEB which lets the PC take direct control of the RF device on the EM over the USB interface.
Currently, SmartRF TrxEB supports:
- CC1120EM
- CC1121EM
- CC2520EM
- CC1101EM
- CC1100EM
- CC1100EEM
- CC110LEM
- CC113LEM
- CC115LEM
SmartRF TrxEB is included in e.g. the CC1120 development kit. Some of the above EMs comes in variants combined with a RF front-end such as CC1190 or CC2590/CC2591. Such variants are called combo EMs and are also supported by the SmartRF TrxEB. See chapter 8 for details on how to use SmartRF TrxEB rev. ≤1.5.0 to control a combo EM using SmartRF Studio.
