The MSP-ISO Isolation board is an easy-to-use plug-in module that offers galvanic isolation between the Debug and Target circuits for MSP430 LaunchPad developers. This is important in cases where the debug circuitry may adversely affect the quality of analog signal measurements made by the MSP430 microcontroller.
MSP430 LaunchPad™ Development Kit designs from Texas Instruments provide an isolation boundary for all signals – including power and data - between the eZ-FET debug probe and the MCU target sections of the board. This isolation is forfeited using the simple jumpers that ship with the LaunchPad. The MSP-ISO Isolation board, though, plugs into this header and connects the signals while maintaining the isolation between the two sides of the MSP430 LaunchPad.
