TRF4903 Demonstration and Evaluation Kit Overview
This chapter provides an overview of the TRF4903 demonstration and development kit.
1.1
Description
The MSP-TRF4903-DEMO kit is used to demonstrate a unidirectional radio frequency (RF) data link
without the need of an external computer, and for prototyping by downloading new software code to the
MSP430F449 through the JTAG connector. This kit is used to evaluate the Texas Instruments TRF4903, a
single-chip multiband RF transmitter. The schematics and layout of the board can be used as a reference
design if desired, limited by the software system parameters of the demonstration firmware.
1.2
Contents
The TRF4903 demonstration and development kit contains:
• One TRF4903 demonstration board (transmitter)
• One TRF6903 demonstration board (receiver)
• User's manual (this document)
Software is not included in the kit. Software and hardware documentation related to this kit can be
downloaded at http://www.ti.com/ismrf.
1.3
Equipment Requirement
The following equipment is not included in this kit and is required to operate the MSP-TRF4903-DEMO kit:
• Four AAA batteries
• MSP430 bus expansion cable for the JTAG connector, required only for prototyping purposes.
