Hardware setup
What do you need?
To use your new LaunchPad, you need to connect an external debug probe to either the 20-pin
LP-EM debug connector on the edge of the board or to the 10-pin debug connector and supply
power separately.

Option 1: Using the LP-EM debug connector
This is the easiest way to setup the hardware. It requires either an LP-XDS110 or
LP-XDS110ET debug probe (sold separately).
Simply connect the connector at the edge of the debug probe to its counterpart on the
LaunchPad and connect the USB port of the debug probe to the host computer. A secondary
UART communications channel will also be available and power to the LaunchPad will be
provided directly.
LP-EM debug connector
Together with a LP-XDS110 or
LP-XDS110ET, allows:
- Debugging and programming
- Communicating to the host via UART
- Powering the microcontroller
10-pin debug connector
Allows using an external JTAG Debug
Probe to debug/program the device

When using the 10-pin debug connector, the UART communications channel must be wired
separately (this connector does not carry UART signals).

Option 2: Using the 10-pin debug connector
Either a standalone debug probe or a separate LaunchPad with a built-in debug probe can
be used.
Connect the two boards as shown in the picture below:
This LaunchPad is great for...
- Battery-operated wireless applications operating in the 2.4GHz ISM RF band
- Add RF capabilities to your product using one of the supported protocols: Bluetooth®5.3 Low Energy,
Zigbee®, SimpleLinkTM 15.4 stack and proprietary protocols
If using a standalone debug probe, consult its documentation to see if it supports the ARM
Cortex-M 10-pin standard.
