MSP430G2553 LaunchPad™ Development Kit (MSP

‑EXP430G2ET)

1. Disconnect every jumper in the isolation jumper block. This is necessary, because the debug probe

cannot connect to more than one target at a time over the Spy-Bi-Wire (SBW) connection.

2. Make sure the target board has proper connections for SBW. Note that to be compatible with SBW, the

capacitor on RST/SBWTDIO cannot be greater than 2.2 nF. The documentation for designing MSP430

JTAG interface circuitry is the MSP430 Hardware Tools User's Guide.

3. Connect these signals from the debug probe side of the isolation jumper block to the target hardware:

•

5 V (if 5 V is needed)

•

3.3 V

•

GND

•

SBWTDIO

•

SBWTCK

•

TXD (if the UART backchannel is to be used)

•

RXD (if the UART backchannel is to be used)

This wiring can be done either with jumper wires or by designing the board with a connector that plugs

into the isolation jumper block.

BoosterPack Plug-in Module Pinout

The LaunchPad development kit adheres to the 20-pin LaunchPad development kit pinout standard. A

standard was created to aid compatibility between LaunchPad development kit and BoosterPack plug-in

module tools across the TI ecosystem.

While most BoosterPack plug-in modules are compliant with the standard, some are not. The MSP-

EXP430G2ET LaunchPad development kit is compatible with all 20-pin BoosterPack plug-in modules that

comply with the standard. If the reseller or owner of the BoosterPack plug-in module does not explicitly

indicate compatibility with the MSP-EXP430G2ET LaunchPad development kit, compare the schematic of

the candidate BoosterPack plug-in module with the LaunchPad development kit to ensure compatibility.

Sometimes conflicts can be resolved by changing the MSP430G2553 pin function configuration in

software.

To check the compatibility of your desired BoosterPack plug-in modules for your design, with a

LaunchPad development kit of your choice, you can use the BoosterPack Checker tool (see Figure 9).

This allows you to select any LaunchPad development kit we offer and determine its compatibility with any

number of BoosterPack plug-in modules that we offer. You can also add your own BoosterPack plug-in

module to check its compatibility as you prototype that next design.
