MSP-EXP430F5438 Experimenters Board

The MSP430F5438 Experimenter Board (MSP-EXP430F5438) is a development platform for the latest
generation MSP430 MCUs. It features a 100-pin socket which supports the

MSP430F5438

(

data sheet

)

and other devices with similar pinouts. The socket allows for quick upgrades to newer devices or quick
applications changes. It is also compatible with many TI low-power RF wireless evaluation modules such
as the CC2520EMK and the TRF7960TB module discussed here in this document.

The Experimenter Board helps designers quickly learn and develop using the new F5xx MCUs, which
provide the industry's lowest active power consumption, more memory and leading integration for
applications such as energy harvesting, wireless sensing and automatic metering infrastructure (AMI).

A TI Flash Emulation Tool, like the

MSP-FET430UIF

is required to program and debug the MSP430

devices on the experimenter board.

The TRF7960TB module plugs into the RF1 and RF2 headers on this MSP-EXP board (see

Figure 3

). For

logic analyzer connection during firmware debug, user can use test points on TRF7960TB board or pins
on header RF3.
